THE VIGILANTE LOVER (3) by Debra Cowan: New SWAT medic Jen Lawson is paired with Walker McClain at the Presley, Okla., fire department. Since Walker's wife and unborn child were killed two and a half years ago by a homeless man, he's felt numb, so he's surprised by his attraction to Jen, who has a secret. Someone dubbed the Payback Killer has killed several homeless men with criminal records, and Jen is an undercover agent assigned to find out if he's that someone. Their relationship heats up, but what will Walker do when he discovers the real reason Jen is working with him? It's obvious from page one that Walker couldn't be the killer, so there's little suspense in this newest addition to the Hot Zone series. But enjoy the ride. This story features a hot romance with sparks galore.
