Becca Ortiz, Los Angeles Police Department psychologist, is fostering teenage runaway Ash.
But Ash can't bring herself to trust a cop, not after what she's been through. Her boyfriend Nate introduces her to the Tribe, his street-smart crew of delinquents and runaways, and Ash finally feels like she's found a home among the homeless.
So one night, she disappears. And as Becca frantically searches for her missing foster daughter, Ash finds herself entangled in the shadows of a criminal underworld, beginning to realise that there may be no way to leave the Tribe without paying a deadly price.
The search for a teenage runaway sends her foster mother, a psychologist working for the LAPD, on a dangerous journey through Los Angeles' criminal underworld, in this gripping new thriller by the author of the international bestseller Baby Doll and The Walls.
