For as long as ten-year-old Moon can remember, he has lived out in the forest in a shelter with his father. They keep to themselves, their only contact with other human beings an occasional trip to the nearest general store. When Moon's father dies, Moon follows his father's last instructions: to travel to Alaska to find others like themselves. But Moon is soon caught and entangled in a world he doesn't know or understand; he's become property of the government he has been avoiding all his life. As the spirited and resourceful Moon encounters constables, jails, institutions, lawyers, true friends, and true enemies, he adapts his wilderness survival skills and learns to survive in the outside world, and even, perhaps, make his home there.

Twelve-year-old Foster knows in his gut that Dax Ganey, the man dating his widowed mother, is a bad seed. Then a mysterious stranger arrives at their Alabama farm, a former Army Ranger in Iraq rambling across the country, and Foster believes he has found an ally against Dax. The stranger proves a fascinating mentor, full of wisdom and secrets. And Dax soon has reason to resent not just him and Foster but also Foster's mother. A spurned Dax will be a dangerous enemy, but Foster is increasingly aware that the stranger is just as dangerous, if not more so.

From the author of one of the most highly acclaimed children's survival adventures of the last decade comes this tautly wound new novel reminiscent of classic westerns, about a boy caught in the middle of a clash that may turn out to be his own battle to fight.
