From Publishers Weekly:
Gudenkauf's tightly plotted debut packs a lot of unsavory doings into a few unfortunate summer days in Willow Creek, Iowa. Seven-year-old Calli Clark hasn't spoken a word in the three years since a particularly nasty run-in with her violent, wife-beating father, Griff. During a bender, Griff suddenly decides to haul his mute daughter into the nearby forest, where they get lost. At the same time, Calli's best friend Petra goes missing, and a manhunt is launched, led by deputy sheriff Loras Louis, who still carries a torch for Calli's mother. Gudenkauf moves the story forward at a fast clip and is adept at building tension. There's a particular darkness to her heartland, rife as it is with predators and the walking wounded, and her unsentimental take on the milieu manages to find some hope without being maudlin.
