The Filthy Claws by J.K. Jones

Death.
Destruction. Decay. All the things that await him if he fails.
War is coming. With it a battle so fierce it could tear a hole through the clans and decimate their way of life. Friends are few and enemies grow increasingly by the day. Not to mention the worst of them all. Ryu’s waking nightmare—the Bloodhound Prince. An evil necromancer spreading the Lycan disease that would eventually kill them all.
To understand the present—he will have to go back to the past.
The Black Shadow must step into the light. No matter how much he rages against it. That means he will have towork with the White Lotus—Micah McCorbyn.
The man he hates beyond all reason.
The man that destroyed his life.
His enemy. His mate.
There is a thin line between them both.
