Secret Self — Claire Farrell

What happens when friend turns to foe?

An attack by a mysterious figure leaves Ava Delaney acting like a feral beast. Believing she's hunting those she's closest to, Peter and Val try to stop her before she either kills someone or is captured by those who would use her.
Morals conflict with loyalties as friends turn on each other, and the only thing for certain is that Ava won't be taken down easily.
