For two sworn enemies, anything can happen during the Hawaiian trip of a lifetime . . .

Olive is always unlucky; her identical twin sister Ami, on the other hand, is probably the luckiest person in the world. About to marry her dream man, her entire wedding has been fully paid for by winning a series of competitions. Meanwhile, Olive is forced to play nice with her sworn enemy: the best man, Ethan.

But Olive's luck may be on the turn . . . When the entire wedding party - except for Olive and Ethan - gets food poisoning, there's an all-expenses-paid honeymoon in Hawaii up for grabs. Putting their mutual hatred aside for the sake of a free holiday, Olive and Ethan head for paradise, determined to avoid each other at all costs. But when Olive runs into her future boss, the little white lie she tells him threatens to spiral out of control.

Forced to play loving newlyweds, she and Ethan find themselves in much closer proximity than they ever expected . . . The problem is that soon, Olive finds that maybe she doesn't mind pretending. In fact, she's beginning to feel kind of . . . lucky.

THE UNHONEYMOONERS is a heartwarming and hilarious romance perfect for anyone who has ever felt unlucky in love.
