Scarlett MacGregor has lived a very sheltered life, courtesy of her over-the-top controlling parents. Having never been to a co-ed party, much less out on a date, Scarlett has relied on her books, music, and living vicariously through her best friend Evie to keep her sanity as she's patiently awaited her freedom from their rule.

When Scarlett and Evie leave home for college, Scarlett soon meets Ashton, Dylan, and Mason, and is thrown into a crash course of like, love, and lust. With Evie's help, she must figure out the difference between the three, and which one she wants, before she ends up without any of them.

Metamorphosis is the beginning of Scarlett's transformation from a young, naïve girl to a strong, mature young woman and her search for self-discovery and true love.
