As book reviews go, every writer has his kin. If you're young, black, Latino, Asian (or preferably some attractive mixture therein), this circle seems to be even more cardinally fixed: Zadie Smith is the new Salman Rushdie, Monica Ali is the British Jhumpa Lahiri, and Chimamanda Ngozi Adichie, says The Washington Post, is the twenty-first century daughter of Chinua Achebe.

Twenty-first century daughter of Achebe? While that particular relationship may take some time to reveal itself, Adichie certainly isn't shy about paying homage to her literary provenance. The first line of her graceful debut, Purple Hibiscus, reads, "Things started to fall apart," echoing Achebe's definitive novel of colonial culture wars, Things Fall Apart. Like Achebe, Adichie grapples with Nigeria 's challenges and contradictions - the remnants of colonialism still within national consciousness, religious fundamentalism (be it Catholic or Muslim), the absurd stigmatization of Hausa-Igbo conflicts - on the grandest scale possible. Still, in these times when lumping any two writers seems increasingly problematic, as Zadie Smith puts it, "catching significant dolphins among such cannable tuna," it's hard not to place Adichie alongside a new generation of post-postcolonial writers who, while paying due respect to Achebe (and, for that matter, Kincaid, Naipaul, Gordimer, and Coetzee), are moving beyond them on their own terms. Harvard's Uzodinma Iweala senior thesis-cum-novel, Beasts of No Nation, depicts a West African civil war in the unflinching pidgin of a child soldier himself. In The Icarus Girl, British writer Helen Oyeyemi blends a precocious English narrator with the ghosts of West African folktales, stubbornly refusing to reconcile one with the other. And Adichie is in the work of breaking that much-touted postmodern maxim, "Show don't tell." While she certainly isn't in the work of sermonizing on the nature of love and war (can she?), her form is, at its heart, anthropological - ethnographic without the detachment, sensitive without the sentimentality. Given the themes of Adichie's stories, you'd expect there to be lots of tears. Adichie's characters aren't the crying types, however. They own up to their vulnerabilities, and when they do finally give in and shed tear, you're probably right there with them.

Adichie is concerned with how big events change little people. While Purple Hibiscus charts the life of a teenage girl during a military coup evocative of the Sani Abacha dictatorship of the nineties, Adichie's Half of a Yellow Sun is more epic in scope, taking on the failed attempt by Igbo secessionists to form an independent Biafran state in the sixties. Half of a Yellow Sun centers on the lives of two very different twin sisters, children of a wealthy Igbo business leader in Lagos. Olanna, who returns from London with a sociology degree, deserts her parents' Anglicized lifestyle for the small, progressive university town of Nsukka. There, she builds a life with Odenigbo, a radical socialist professor, who lives with his devoted houseboy, Ugwu. However, Kainene, Olanna's dark and pragmatic twin, is wary of her sister's naïvete and the rhetoric of her "revolutionary lover." Kainene remains committed to her father's oil ventures and falls in (and out) of love with a man very different from Odenigbo, Richard Churchill, a shy English writer both intrigued and intimidated by Kainene's strength. As Odenigbo puts it, however, "The real tragedy of our postcolonial world is not that the majority of the people had no say whether or not they wanted this new world; rather, it is that the majority have not been given the tools to negotiate this new world." Adichie sets up these personalities - Kainene's pragmatism and Olanna's idealism, Odenigbo's confidence and Richard's idealism - as often just as confused with the Nigeria they've inherited as they are with each other.

For each of these characters, therefore, the political is inextricably and intensely personal. Odenigbo, at one of his dinner parties before the war, declares: "I am Nigerian because a white man created Nigeria and gave me that identity. I am black because the white man constructed black to be as different as possible from his white. But I was Igbo before the white man came." Odenigbo's essentialist self-righteousness, his sensationalized elevation of the tribe over the nation, remains nothing more than loosely clustered ideals. His activism is reduced to self-fulfilling prophecies, pamphlet writing, or political sermons to the like-minded choir of Nsukka intellectuals. In the domain of his own house, he is able to toast to other progressive movements:

'To that brave, black American led into the University of Mississippi !' 'To Ceylon and to the world's first woman prime minister!' 'To Cuba for beating the Americans at their own game !' - and Ugwu would enjoy the clink of beer bottles against glasses, glasses against glasses, bottles against bottles.

Odenigbo romanticizes these causes, however, as their full complexities are lost in the clinking of bottles and glasses. Ugwu's confusion is our confusion. Yes, Odenigbo champions these causes from Mississippi to Ceylon, but his political speeches are little more than highly-charged rants from a privileged distance. He is always one step removed from the fray. Richard observes that "here was a man who trusted the eccentricity that was his personality, a man who was not particularly attractive but who would draw the most attention in a room full of attractive men." Is Odenigbo's activism a cry for attention? Probably not. But many of his political tirades seem to be a cry for help, as if all his training is futile in Nigeria 's rapidly changing political climate. His whole character asks readers to consider what function theory serves in a society for which theory seems all too inadequate.

Adichie suggests that boardroom politics do not make the war, but "[what] mattered was that the massacres made fervent Biafrans out of former Nigerians." As with Purple Hibiscus, however, Adichie's patient descriptions are often more affecting than her broad social arcs. In Adichie's world, Odenigbo is not simply a professor defeated by his environment. Rather, he appears through Ugwu's eyes: "the deep voice, the melody of the English-inflected Igbo, the glint of the thick eyeglasses." Children are not sentimentally victimized; rather, a toddler is described as "playing with a collection of old shrapnel." Rape is not abstractly rape; the rapist is instead reduced to his cowardly thrusts, "his small buttocks darker-colored than his legs." The young soldier does not simply maim and kill; in the trenches, he "[luxuriates] in how close and connected he was to the mud." Adichie does not shirk from chaos; rather, her sentences remain indeterminate: the " ka-ka-ka of shooting, the cries of men, the smell of death, the blasts of explosions above and around him were distant."

In this indeterminacy lies Adichie's complex approach to war. Half of a Yellow Sun does not reductively portray Hausa qua Hausa or Igbo qua Igbo. In Adichie's stories, people play roles - for good and for ill. Hausa men are able to shelter their Igbo friends from attacks. Western Igbos are capable of masking their identities with a simple switch into a Yoruban tongue. The West, furthermore, is intricately implicated in Africa 's political fabric. Adichie ties Nigeria 's conflicts to the historical legacies of British colonial rule: "The British preferred the North. The heat there was pleasantly dry; the Hausa-Fulani were narrow-featured and therefore superior to the negroid Southerners." Those same perceptions illumine the mindsets of some in Nigeria 's contemporary expatriate community. One British woman remarks: "There are lots and lots of Igbo people here - well, they are everywhere really, aren't they? Not that they didn't have it coming to them, when you think about it, with their being so clannish and uppity and controlling the markets. Very Jewish, really."

Adichie's nuanced prose takes great pains to undo the reductive attitudes many in the West harbor toward African people. While on a journalism assignment in Biafra, for example, Richard discovers that "human angle" carries entirely different connotations for Western consumers:

The international press was simply saturated with stories of violence from Africa, and this one was particularly bland and pedantic, the deputy editor wrote, but perhaps Richard could do a piece on the human angle?... 'Did they mutter any tribal incantations while they did the killings, for example? Did they eat body parts like they did in the Congo ? Was there a way of tying truly to understand the minds of these people?'

And yet Adichie does not rant against the West. In her descriptions of American journalists, criticism and compassion coexist. She understands that it takes many hands to shape war, that the suffering of a Biafran girl who lost her brother in an air raid and the suffering of a red-headed American journalist "who brought [his] kid brother's body back from Vietnam last month for God's sake" share some common axis. Charles, one such American journalist, in his half-hearted way, continues: "'People are dying everywhere.' He sat down on the floor." In two lines, Charles connects to the thoughts and movements of thousands of Nigerians. For Adichie, pain unifies us, and it's often that same pain that keeps us from recognizing that unity.

However, Adichie is aware of the inability to completely capture Nigeria 's war, all while motivated by the strange impulse that its horrors need to be recorded. Towards the end of the novel, we discover that one of Adichie's only truly redeeming characters is the author of a book manuscript that is excerpted at the end of several chapters of Half of a Yellow Sun, entitled "The World Was Silent When We Died." If anything, writing for Ugwu (and Adichie) is a protest against this silence. When witnessing a little Igbo boy, Ugwu may have put it best: he both "realized that he would never be able to capture that child on paper, never be able to describe well enough the fear that dulled the eyes of the mothers in the refugee camp, when the bomber planes charged out of the sky," but he was resolved that he needed to write because, if for nothing else, the "more he wrote the less he dreamed."

Ultimately, the good of Adichie's novel is her constant reminders of her own limitations, a narrative humility coupled with an epic ambition. Adichie's chapters constantly end with tears, fragile clasps, hands slipping away. Every page seems to beg the reader to meditate on those slippages, asking, "What kinds of force really change a little boy into a teenage soldier?" Or a mathematics professor into a socialist radical? Or the writer into a silent bystander? But like our best novelists, Adichie's indeterminacy isn't a full abandonment of her characters' hopes. Rather, they provide a space for her characters' complexities to thrive. Are there any easy answers in Adichie's novel? Certainly not. But Adichie, in the process, asks the hell out of her questions, rendering them in all their haunting, beautiful salience.
