The New York Times bestselling authors of The Unhoneymooners present a charming, laugh-out-loud novel filled with adventure, treasure, and, of course, love. Lily has never forgotten the man that got away . . . but she certainly hasn't forgiven him either! As the daughter of a notorious treasure hunter, Lily makes ends meet using her father's coveted hand-drawn maps, guiding tourists on fake treasure hunts through the canyons of Utah. When the man she once loved walks back into her life with a motley crew of friends, ready to hit the trails, Lily can't believe her eyes. Frankly, she'd like to take him out into the wilderness - and leave him there. Leo wants nothing more than to reconnect with his first and only love. Unfortunately, Lily is all business: it's never going to happen. But when the trip goes horribly and hilariously wrong, the group wonders if maybe the legend of the hidden treasure wasn't a gimmick after all. Alone under the stars in the isolated and dangerous mazes of the Canyonlands, Leo and Lily must decide whether they'll risk their lives, and their hearts, on the adventure of a lifetime . . .
