The mystery of their lives.

La Capitana and the other teens of the Neighborhood Watch have spent their entire lives wondering why they have parahuman powers but not the genetic marker known to grant them. When their former rivals, the Arnold triplets, come to La Capitana with a lead on the source of their powers, she jumps at the chance to join Brittany, Brianna, and Brooklyn.

Truth and its consequences.

Their investigation takes them across the country to New York City, where the four girls discover their abilities have a more sinister origin than they could have imagined. The question is, what will they do with their newfound knowledge, and can they triumph over the trouble that comes with it?
