Pax and Peter have been inseparable ever since Peter rescued him as a kit. But one day, the unimaginable happens: Peter's dad enlists in the military and makes him return the fox to the wild.

At his grandfather's house, three hundred miles away from home, Peter knows he isn't where he should be—with Pax. He strikes out on his own despite the encroaching war, spurred by love, loyalty, and grief, to be reunited with his fox.

Meanwhile Pax, steadfastly waiting for his boy, embarks on adventures and discoveries of his own. . . .

A Long Walk to Water begins as two stories, told in alternating sections, about two eleven-year-olds in Sudan, a girl in 2008 and a boy in 1985. The girl, Nya, is fetching water from a pond that is two hours’ walk from her home: she makes two trips to the pond every day. The boy, Salva, becomes one of the "lost boys" of Sudan, refugees who cover the African continent on foot as they search for their families and for a safe place to stay. Enduring every hardship from loneliness to attack by armed rebels to contact with killer lions and crocodiles, Salva is a survivor, and his story goes on to intersect with Nya’s in an astonishing and moving way.

Inspired by the author's childhood experience as a refugee—fleeing Vietnam after the Fall of Saigon and immigrating to Alabama—this coming-of-age debut novel told in verse has been celebrated for its touching child's-eye view of family and immigration.
