Grayson Ames and the Nightmare Patchwork

What if the person you hated most was the only one who could save you?
Life is miserable when you have destroyed the only things you've ever loved. Grayson Ames knows that better than anyone.
So his answer to the life-crushing events that took place on Halloween is simple: die.
But death does not come easily to someone tethered to an elder vampire. Yet no matter how hard he tries, he can’t seem to end his own life.
 
And that’s when his dad shows up.
 
After a decade, the man who cursed Grayson appears at his door, asking for help. Damien Ames needs to find Project Patchwork. If he does, he might be able to remove Grayson’s tether. But it won’t be as simple as a regular bounty. The Patchwork Project is more complicated than anything Grayson has seen before. And the more he discovers, the more tangled this mysterious prod becomes.
Mysterious and impossible.
Patchwork is killing with powers no mortal should have. If Grayson can work with his father, he may be able to unravel this monstrosity before he loses his one chance to die.
