Ruthless Creatures (Queens and Monsters Book 1) by J.T. Geissinger

Five years ago, my fiancé disappeared. He left me with a wedding dress I'd never wear. Left me with the kind of scars that can't be healed. The man I built my future on vanished like a ghost. All that remained were my broken heart and a million unanswered questions.

Until a mysterious stranger arrives in town.

Tall, dark, and dangerous, Kage is as full of secrets as he is sex appeal. Though I know he's hiding something, I'm drawn to him like a moth to flame. Heat crackles between us with every look, desire flares into passion, and I fall hard, helpless to resist.

But then I discover he's been sent to collect on an unpaid debt from my missing fiancé. . . .

And that debt is me.
