"Elite Guardian Charlie Lee knows that there is no future with the woman he loves--fellow Guardian Lizzie Tremaine. And he gets it. Lizzie's a single mom focused on protecting her daughter, and Charlie's got his own baggage anyway. It's easier, and safer, to keep things the way they are. Then, the unthinkable happens. While Charlie is undercover, he's seriously injured...and his memory of the past four years is gone. But maybe it's the fresh start he didn't know he longed for. And now he's getting too close... Lizzie cares for Charlie, but she's lost all the men she's ever loved and can't risk her heart again. Still, she's determined to protect Charlie, and help him discover who attacked him--and why. But in the process, she begins to discover an unburdened, impossible-to-resist version of the man she knows. And--along with the details of his attack--Charlie seems to have forgotten their reasons for keeping things platonic. Suddenly, all of their self-imposed rules are gone, and Lizzie needs things to get back to normal, stat. It's her heart... or his life. Problem is, the closer Charlie gets to uncovering his memories, the closer he gets to trouble. What will protecting Charlie cost Lizzie?"--Amazon.com.
