When having two powers makes you a Super and having none makes you a Normal, having only one makes you a sad half-powered freak. A One. Merrin would love to be able to fly-too bad all she can do is hover. Her mad chemistry skills land her a Biotech Hub internship, but as she gets closer to the life she always wanted, she discovers that the Hub's purpose is more sinister than it seemed. Now she must decide if it's more important to fly solo, or to save everything-and everyone-she loves.
