In the small town of Mud Creek, nothing ever happens. But when Ivy's twin sister Lily blackmails her to switch places for three weeks, she finds that her life is anything but simple. Ivy knew that fooling her sister's best friend and boyfriend would be hard enough, but she didn't count for one obstacle: Nick.
With his blue eyes, blonde hair, and charming smile, Ivy had been crushing on him since forever. But there was one problem: Lily already had a boyfriend. If Ivy wants to keep the act going, she can't show Nick how she truly feels. But things get complicated when she starts to think that he may feel the same way. The issue: he thinks she's Lily.
Now, Ivy has to decide between what's right and what she wants. Through it all she learns a valuable lesson: keeping a secret is never easy.
