Book-loving librarian Jessie has loved Gavin Williams for practically her whole life. So when a psychic predicts that Gavin is Jessie's one fated soul mate, she's ecstatic. 

There's just one itty bitty little problem.

Gavin's engaged to marry another woman. 

What's a book lover to do? Easy. Check out dozens of romance books, study the (totally realistic) way characters fall in love, and make a foolproof plan on how to win her soul mate (in one week). 

Meet cute? Check.

Dance under the stars? Check.

Kiss in the rain? Check.

Romance books don't lie – it'll all go perfectly.

Except, there's another problem. Gavin's twin brother: William Williams IV. 

Jessie has hated William for as long as she's loved his brother. William is grump to Jessie's sunshine, stand-offish to her extrovert, cold to her warm. And when William learns of Jessie's plan to derail his brother's engagement he swears that he'll do anything to stop her.

But after William and Jessie (unwillingly) share a dance…a romantic dinner…a kiss…Jessie starts to wonder, is William actually her soul mate? Or is this just another one of his games? 

She can't tell, because this romance definitely isn't going by the book.
