Banker Katie James has a serious thing for romance novels. She'd almost rather settle for a fictional boyfriend than risk her heart on a flesh-and-blood man. Besides, the only real guy she's remotely interested in is her rich, unattainable client, the mysterious Cooper Maxwell.

Looking less like the ultra-conservative man she knows and more like a drop-dead sexy character from one of her books, Cooper crashes Kati's 29th birthday party. But one too many drinks lands Katie in uncharted territory...Cooper's bedroom!

Drunk on love, Katie dives headfirst into the relationship only to discover that Cooper is keeping secrets...dangerous ones. As if things couldn’t get worse, her meddling mother makes a surprise visit, digging up a whole new set of problems.

Who would have guessed having an assassin for a boyfriend would be the least of her worries?
