Protector. Mind Games, #5

A highly trained assassin lies bound hand and foot, wounded and helpless. His abductor: his own brother. Bryce has never stopped searching for his missing brother. Twenty years have passed since the twelve-year-old Zach was snatched off the street, but a big brother's duties don't end that easily. He's about to give up hope when he gets the news: one of his hired investigators has tracked Zach down.
Bryce can finally bring him home-whether Zach likes it or not. Zach barely remembers his childhood. Or the days when he used to fear his abductors. Now they're his home. His family. The ones who taught him about the supernatural gift he didn't know he possessed, and showed him how to use it for the greater good. Bryce wants to save his brainwashed brother. Zach wants to go home. But when Zach's employers hunt him down, they don't have the luxury of treating each other as the enemy anymore.
Now they both want the same thing:To protect their brother.
