When Ellie’s fiancé cheats on her with a younger and slimmer blonde from the office, she boots him out of her life and finds solace in a fabulous photography job aboard a Caribbean cruise ship. Twenty-four hours on board and she’s already shagged her sexy Texan colleague, who happens to love her muffin-top. Unfortunately, he’s leaving in a week, and his ex-girlfriend, a hot-headed Brazilian with stripper moves right out of the 90s and a talent for stealing boyfriends, is still on board and out for revenge.

Ellie must work out how to deal with the loco ex, sort the lying scumbags from the good guys, and figure out how many crew members in a cabin it takes before officially becoming group sex. Who the hell knows? (It’s five, actually.) It’s a world completely unlike the one she left behind, but as she tries to find her place on board, Ellie discovers laughter and tears in equal measure. And in the midst of the craziness, she realises the greatest thing this lifestyle change has given her is the chance to rediscover herself.
