Devyn Ruth was little miss perfect. She's the kind of girl who always follows the rules - at least on the outside. But when her family left Boston for a mansion in St. Louis nearly five years ago (all for the sake of her parents' status and hospital promotions for their prestigious careers in medicine) Devyn started to feel the cracks. The pressure, the expectations, the suffocating performance of being the perfect daughter. She's a chemistry major at Tufts (a desperate attemp to grasp onto what her life before the move felt like) with her whole future mapped out: med school, internships, a life her parents can brag about. But under the surface, Devyn's barely holding it together. She's tired of pretending, tired of hiding in the closet, tired of doing everything right and still feeling like a fraud.
Reagan Miller, a 22 year old teenager, is the opposite in every way. Tattooed, outspoken, proudly gay, and constantly challenging authority, she's the counselor kids idolize and adults roll their eyes at. Reagan doesn't need people to like her - she just needs to survive the summer without getting fired. Again. Since her mother left without warning in her early teen years, Reagan has been desperate to support her father. He was a kind man, a diabetic who was aging much too fast for her liking. He had done everything for her, and so Reagan didn't think twice about abandoning her dreams of moving to New Orleans to become an artist. It simply wasn't in the cards for her.
They've hated each other for years. Maybe because they're too different. Maybe because they're too similar. Either way, when a group of campers locks them both inside Cabin Thirteen as a joke, Devyn and Reagan are forced to spend a long, sweltering night trapped together - and neither of them is ready for what surfaces when the doors close and the masks start to slip and secrets begin to come out.
Annabeth Reed had simple goals in her life, graduate at the top of her class, get a nice boyfriend and mostly win the scholarship to her dream art school. She had everything she could wish for a set of supportive parents, an annoying but lovable older brother, and two amazing best friends, but her life would have been so much better if not for her.
Emmalyn Cole also known as the school's sweetheart was the exact opposite. She was bright, loud and the absolute center of Rosewood High. Being the daughter of a self-made businesswoman and a famous pianist, she knew she was destined for greatness, but in sophomore year when she was publicly dumped by her boyfriend for her sister, she felt her friends and life slipping away. Junior year she knew that the scholarship to the art school her sister wanted would be her saving grace. She would easily get in if not for her.
What started as a small competition spanned into a decade-long rivalry between the two girls. Both ambitious and always after excellence. With the turn of fate, they are once again competing head-on with each other.
With the growing competition, a new boy comes along catching everyone's attention including those two and soon they find themselves competing for something other than the scholarship.

As the days pass and they grow closer, the girls find themselves questioning is he the one? or are they each other's perfect half?
