When having two powers makes you a Super and having none makes you a Normal, having only one makes you a sad half-superpowered freak. 
It makes you a One. 
Sixteen-year-old Merrin Grey would love to be able to fly – too bad all she can do is hover. 
If she could just land an internship at the Biotech Hub, she might finally figure out how to fix herself. She busts her butt in AP Chem and salivates over the Hub’s research on the manifestation of superpowers, all in hopes of boosting her chances. 
Then she meets Elias VanDyne, another One, and all her carefully crafted plans fly out the window. Literally. When the two of them touch, their Ones combine to make them fly, and when they’re not soaring over the Nebraska cornfields, they’re busy falling for each other. 
Merrin's mad chemistry skills land her a spot on the Hub's internship short list, but as she gets closer to the life she always wanted, she discovers that the Hub’s purpose is more sinister than it has always seemed. Now it’s up to her to decide if it's more important to fly solo, or to save everything - and everyone - she loves.
