Will North and his little sister Wenny both die when they are hit by a truck, but he is pulled back into life. Will blames himself for Wenny's death--and he is furious with Wenny for leaving him behind. Will's pastor tells him that when he's angry, he writes letters to God, but Will decides he'd rather write letters to Wenny. So he does, in a touching, funny, and honest correspondence.
In the fight with the truck barreling toward them, Wenny and Will lost big. Wenny lost her life. Will lost a sister -- and lost faith in himself.
But then Will starts writing letters to Wenny. He tells her all about the secret of his near-death experience, and the troubles he's having at home. Some letters are funny. Some letters are harsh. And when read together, they tell the story of a boy who finds a way to move past death and learns how to live again....
