Famine by Laura Thalassa

They came to earth—Pestilence, War, Famine, Death—four horsemen riding their screaming steeds, racing to the corners of the world. Four horsemen with the power to destroy all of humanity. They came to earth, and they came to end us all.

Ana da Silva always assumed she’d die young, she just never expected it to be at the hands of Famine, the haunting immortal who once spared her life so many years ago. But if the horseman remembers her at all, he must not care, for when she comes face to face with him for the second time in her life, she’s stabbed and left for dead.
Only, she doesn’t quite die.

If there’s one thing Famine is good at, it’s cruelty. And how these blighted bastards deserve it. Try as he might, he can’t forget what they once did to him. But when Ana, a ghost from his past, corners him and promises pain for what he so recently did to her, she and her empty threats captivate him, and he decides to keep her around.

In spite of themselves, Ana and Famine are drawn to each other. But at the end of the day, the two are enemies. Nothing changes that. Not one kind act, not two. And definitely not a few steamy nights. But enemies or reluctant lovers, if they don’t stop themselves soon, heaven will.
