Summary:

Kat, a Powered with superhearing, is on her way to deliver a letter that will change her future. She plans on going undercover at a suspected crime school, and this letter will be the ticket she needs for that fate.

Liam, a Powered with the odd ability to create cotton candy, is rushing a letter filled with his course selection for his new high school. He dreams of discovering the truth behind his parents' alleged death.

When they collide, they discover more about the world that they live in. Kat discovers that there's a traitor at the police academy where she's staying . . . and they're determined to wipe all Powered from the face of the planet. 

Along their journey, they meet several people willing to help them with their goals, but one of them is just a little too eager to stay with them, no matter the cost or lives taken in the process.
