He is... Creed Part One. Windwalkers, #1

He is... Creed, a soldier lied to and turned into a weapon by his own country. She is the light to the darkness inside him. The only person who can save him from the monster he might become. The only person who can save the world from what he might become. Creed is one of the soldiers who were lied to and injected with an experimental serum at Area 51, a soldier whose unique ability to travel within and communicate with the wind makes him his country's greatest weapon.
Within him is a great power, and a darkness, he secretly fears he cannot control. He is losing himself and his humanity and he doesn't know how to stop it from happening. But then he meets Addie, the beautiful and intelligent scientist and the daughter of the man who did this to him, who's come to right her father's wrong. The minute they connect, he feels drawn to her. The minute he touches her, he feels the darkness inside him calm, and an obsessive passion stirs between them.
Possessiveness rises inside Creed and his desire for her is all consuming. Soon though, they will learn that Addie is his one true mate, his lifebond, the light to his darkness. A phenomenon no one quite understands and must be kept secret. But even as their bond develops into something greater than they imagined possible, danger erupts as some of Creed's kind rise up and become a threat. Creed is the soldier powerful enough to end it all, but as he calls on that part of himself, the darkness stirs.
The bond between Creed and Addie might be the only thing that saves the world. It also might be the death of Addie.
