Their letters could lead to lasting love . . . or expose Sabrina's mortifying secret.

Sabrina Kincaid didn't intend to fall for Nantucket native Tucker McCabe, the man she serves coffee to every morning-a man tied deeply to a past she deeply regrets. But she has. And she's fallen hard.

But she's kept this a secret from her handsome customer. And now Tucker wants to hire Sabrina to help locate his friend "Sweetpea"-the mysterious woman he's falling in love with online. Sabrina is not inclined to help, but if Tucker hires someone else, it could spell disaster. Because if someone else sifted through the emails and figured out the truth-then Tucker would discover that the person he's trying to find is . . . "her."
