"She's on a mission to save lives. When one of her students becomes the latest victim of a D.C. gang-slaying, sociology professor Trevy Barlow is determined to protect the other girls in her literacy class for at-risk teens--even if it means compromising her own safety. He's on a short clock to find a killer. FBI gang task force agent Cruz Larsen isn't about to let Trevy endanger herself or sidetrack his investigation with her do-gooder meddling. But when a key witness refuses to talk to anyone except her, Cruz has to find a way to earn her trust so that she'll play by his rules. Now a sadistic predator is after them. For Cruz, keeping Trevy safe has become more than a duty--his heart is involved too. But all of his leads have flatlined. And he's beginning to suspect that a hidden third party has rekindled the gang rivalry for reasons far beyond a D.C. turf war. Caught in the crossfire, Trevy will have to risk it all to give them a fighting chance to survive." ... amazon.com.
