I refuse to give my heart to any man again. Especially not one who is a playboy firefighter.And definitely not my brother's best friend...It doesn't require being a former cop or having my PI license to know that Don Alvarez thinks he's smoking hot. I'm surprised the Rescue Four's fire investigator has enough energy left to investigate fires with all the women he has lined up.But when my brother gets injured on the job, Don's sense of duty propels him to track down the arsonist before anyone else gets hurt. And my connections are just what he needs to help him make a breakthrough on the case.I refuse to fall victim to another womanizer, although if teaming up with Don means getting justice for my brother, I'll take the heat. But, wow, is it hot around here since I've discovered there's more to Don than his charming bravado.With a heart bigger than his reputation, and wicked sense of humor guaranteed to make me laugh, the sexy firefighter has a way of burning straight past my defenses.But when the arsonist sets their sights on me, I think I've made the mistake of realizing my true feelings too late...
