Forbidden fruit... Reed, Noelle, and former Billings Girls Kiran and Taylor have been living it up on St. Barths over winter break. The tropical sun has melted away all the tensions of last semester, and for the first time in months, Reed is happy. She's got her best friends by her side, she has a palatial suite with an ocean view, and she's landed Upton, the most sought-after guy on the island.

Reed is falling in love.

But dating Upton makes Reed St. Barths' highest-profile guest -- and not in a good way. Upton has a dark past, and he's broken a lot of hearts. One of his exes still wants him. And she'll do whatever it takes to get Reed out of the picture.
