I spent centuries avoiding romantic entanglements. Who wanted to be burdened by feelings? But then she happened and it didn't matter what I wanted anymore.

Living with a succubus was never going to be easy but when we lose Merri to her demonic side the only way to bring her back is to give in. The one thing I'd spent so long trying not to do.

I'm pretty sure I coined the term workaholic. Plagues were what I lived for. Who could blame me? After my disastrous attempt at being a family man I locked myself away and focused on the only thing that truly mattered. Self-preservation. And if I happened to end the world in the process? Well, bully for me.

Now here I am with my entire life plan turned upon its head. I haven't thought about my duty as a horseman in weeks. Instead, my mind is consumed with my hellcat.

She's clawed her way past my defenses. All of our defenses.

Sin is already kneeling at her feet.

Chaos is well on his way.

Grim would be right there beside them if it wouldn't kill her.

And me? I'm barely hanging on by a thread.

No matter how many times I tell myself I can resist, falling for her is a foregone conclusion. She's the most powerful antigen I've ever come across, and I'm far from immune. Which should make it easy in the end.

Except I know how this story goes. There's no such thing as happily ever after for the four horsemen. Merri was never ours to keep.

For fans of Supernatural and American Horror Story, USA Today bestselling authors Meg Anne and K. Loraine are thrilled to bring you the final installment in the Mate Games Universe.

Warning: The Mate Games: Apocalypse is a spicy paranormal series featuring morally gray heroes whose methods of protection aren't always above board. Not that you can expect much honor from a celibate recluse, an incubus rockstar, the original shadow daddy, and a grumpy ex-Spartan. They are the Four Horsemen of the Apocalypse, after all.
