Tobias “Slim” Jackson has the perfect life as a pilot on Gansett Island in the summer and in Florida in the winter. He's happiest when he’s in the air, or at least that was the case before last summer when he met Erin Barton, Gansett Island’s newest lighthouse keeper. Now he can't seem to find his usual enthusiasm for flying, winter in the sunny South, or anything that doesn’t include her. Erin has been stuck on pause since she lost her twin brother. She'll tell you herself that her life has been a hot mess since Toby died. After dropping out of law school, she flits from one pointless job to another, existing rather than truly living. Then she comes to Gansett Island to take over as the new lighthouse keeper and meets Slim, who happens to share her beloved brother’s first name. That small coincidence is enough to convince her that she needs to spend more time with the dashing pilot—except for the fact that he’s spending the winter more than a thousand miles from her. Now Slim’s come home to Gansett for the holidays and hopes to pick up where he left off with Erin. He's got twelve days before he’s due back in Florida to finish out the remainder of his winter obligations. A lot can happen in twelve days, but will it be enough to convince Erin that it's time to start truly living again?
