The deep end

"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."--Publisher.
