"A Callaway family novel."

"FBI agent Kate Callaway is on her way to San Francisco for a family wedding when her boss asks her to make a side trip to deliver an important message to a rogue ex-agent. Devin Scott wanted FBI resources to find a serial killer who is believed to be dead. Instead, he gets a newly minted agent who is a beautiful, idealistic and irritating distraction. He wants her to walk away, and she knows she should go...but she can't. Suddenly, Kate is caught up in a cold-case mystery and the arms of a dangerously sexy man, whose obsession with truth and justice could put not only his life on the line but also hers."--from back cover
