Her Soul for Revenge by Harley Laroux

Zane
I've been hunting souls for centuries, but she's the ultimate prize - vicious and feral, with a broken soul as dark as my own. I thought claiming her would be a simple game, but Juniper is far from simple. I chose to follow her on a path drenched with the blood of her enemies, but it's our blood that may be spilled next. As an ancient God wakes from Its slumber, neither of us may survive.
