An Indigo Wind (The Four #2)

Firefighter Gianna Fallon struggles to hide her unusual talents – especially her ability to control fire. But when she and Callan Doyle are tasked with taking down a compound creating warriors with superpowers, both will need every tool they possess.

Callan Doyle, surfer and former SEAL, hates what happened when he began receiving the mysterious injections that changed who he was. Still, he'll use those changes to help destroy that compound.

But a powerful evil hides in plain sight in the compound, making their task more treacherous. As a net slowly surrounds them, can they neutralize the evil in the compound before the net pulls tight and evil eliminates them?
