A romance on an epic, generation-spanning scale, Mae Marvel’s The Guest Book delivers the authors’ signature heart, sapphic steam, and humor in a book you’ll curl up with and never forget.

The whole world believes Cosima Frank’s life has been a fairytale. Now she’s trying to live up to the overwhelming legacy left to her by her late mother, the Queen of Hollywood. As the pressure begins to build, Cosima does the only thing she can think run straight to the inn where her parents met and fell in love, intent on finishing her mother’s bucket list.

Edie Whitelock isn’t like anyone Cosima has ever met. She’s persistent enough to march up to Cosima’s door and provoke her to get out of bed and follow the disarming woman through the charming English village. Edie’s also on the run from her past, but she finds that she relishes bickering with the pretty Los Angeles princess a whole lot more than she expected. The two women couldn’t be more different, but they find themselves inexplicably drawn to each other.

Trapped indoors by thunderstorms, Cosima and Edie discover the inn’s guest book, whose entries date back more than fifty years—and inside it, a romantic treasure hunt left behind by a long-ago guest whose clues unexpectedly send them across England, Spain, and France on an adventure they hope will change both of their lives.

But sometimes the treasure you seek isn’t the one you find.
