Apollo Battleson knows what it is to be down and out.

He's come a long way since poverty and tragedy launched him into a soul-crushing journey through the juvenile court system.

Now he's a doctor, a decorated former SEAL, and a self-made man.

He's also the guy who keeps his pack of alpha brothers alive as they tackle some of the world's most dangerous missions.

But that all changes when he meets a mysterious woman who goes by the name "Blue."

And she might just put him in more danger than even he can handle.
