Kori Anders' summer job at a ritzy Santa Monica beach club is fun, but she doesn't feel like she belongs there. She never breaks the rules, she doesn't care about keeping up with the current trends, and she can't be bothered rushing around to make an appearance at all the parties--in fact, Kori avoids rushing at all costs because of her Ehlers Danlos Syndrome diagnosis. What she does feel is an inexplicable draw to the stars.

Her older sister, Kira, on the other hand, is the most popular girl around. With the hottest clothes, an even hotter boyfriend (the Tate Fairweather), and a take-no-prisoners attitude, she's Kori's opposite in every way. Sadly, Kori doesn't think Tate is a good fit for her sister, and nothing she says will convince Kira to break up with him.

The summer heats up when Tate's uncle, Lynch Fairweather, CEO of a major pharmaceutical company, asks Kori and Kira to participate in a clinical trial designed to advance treatments for EDS. During treatment, Kori begins to discover some strange powers that she has never had before...and she might not be the only one.

Can Kori uncover the truth about her powers and find a way to persuade her sister to trust her before it's too late?
