The unhoneymooners- Christina Lauren

Olive is always unlucky; her identical twin sister Ami, on the other hand, is probably the luckiest person in the world. While she's about to marry her dream man, Olive is forced to play nice with her nemesis: the best man, Ethan.

Yet 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, Olive and Ethan head for paradise. But when Olive runs into her future boss, the little white lie she tells him spirals out of control.

Forced to play loving newly-weds, she and Ethan find themselves in closer proximity than they ever expected.

Soon, Olive finds that maybe she doesn't mind pretending.

In fact, she's beginning to feel kind of... lucky.
