After helping to convict two men who planned to sell Redstone Inc. secrets, Lilith Mercer has a series of accidents. She thinks it's a coincidence, but Josh Redstone turns things over to his security team. Former gang member turned ace investigator Tony Alvera offers to look into it. Tony and Lilith lock horns over the situation, while fighting their attraction. Even after everything is blown wide open, it takes some nudging to admit what's happening. With this addition to the Redstone Inc. series, Justine Davis does her usual tremendous job of giving her readers a well-crafted tale. But the real pull in Backstreet Hero (4) is a combustible couple who almost let some perceived obstacles get in the way of their future happiness.
