The Deep End — Debra Purdy Kong

Transit security officer Casey Holland's latest assignment  -- to monitor a group of teens riding the M5 bus after shoplifting sprees  -- spirals out of control when the kids attack her and her colleagues. Compounding Casey's stress are the manipulative boy her 13-year-old ward, Summer, is dating, and the intense volunteer work she's doing at Fraserview Youth Custody Center. Casey's shocked to find a friend's grandson, Justin, inside the center. Shock turns to horror when the facility's director suffers a fatal heart attack in front of her. A second death and rumors of illegal activity at Fraserview make Casey wonder whether Justin is part of the problem or a potential victim. As Casey deals with troubled teens on all fronts, the escalating violence could change her and Summer's lives forever. Who will live and who will die? The fourth installment in Debra Purdy Kong's Casey Holland Mystery series will keep readers guessing right to the end.
