Returning to Castle MacPherson was definitely not FBI profiler Duncan Sutherland's choice. But when defense attorney Piper MacPherson is targeted by a serial killer, Duncan knows it's the only place she'll be safe. At least, safe from her stalker. There's no guarantee he'll be able to keep his hands off her…. Little does Duncan guess that Piper has always wanted him, too. In fact, years ago, she'd written down her most intimate fantasies—all of them involving on-demand sex…and him. Now though, she wants the real deal. And with a serial killer threatening her life, the best thing Duncan can do is provide Piper with full-body cover—day and night!
