From the New York Times bestselling author of In Five Years comes an intensely romantic modern recounting of the greatest love story ever told—narrated by the girl Romeo was supposed to love.

Rosaline knows that she and Rob are destined to be together. Rose has been waiting for years for Rob to kiss her—and when he finally does, it's perfect. But then Juliet moves back to town. Juliet, who used to be Rose's best friend. Juliet, who now inexplicably hates her. Juliet, who is gorgeous, vindictive, and a little bit crazy...and who has set her sights on Rob. He doesn't stand a chance.

Rose is devastated over losing Rob to Juliet. And when rumors start swirling about Juliet's instability, her neediness, and her threats of suicide, Rose starts to fear not only for Rob's heart, but also for his life. Because Shakespeare may have gotten the story wrong, but we all still know how it ends.
