His Soul To Keep — Rachel Leigh Smith

To save his soul, he risks condemning the world.
Boulder pride security chief Gabe Kincade is losing his mind. It's the only explanation for remembering a past life in ancient Egypt as one of Maahes's warriors. Meeting a gorgeous scientist his jaguar says is his mate is a complication he can't afford -- and can't resist. Ares is after him, and if the god catches him, he's dead. Again.

Wildlife geneticist Autumn Dailey has spent the last fifteen years tracking big cat DNA. She's on the verge of a huge discovery, and the key might be in the samples from her cougar population study. Being kidnapped by people who turn into cougars proves she's found her something huge. Gabe Kincade showing up and promising to protect her from an unhinged alpha is an unexpected bonus. So is falling in love with him.

But Ares knows who Gabe really is and what he can do. The Greek god of war will do anything to take possession of his soul. Including using his past life to destroy his future. To save Autumn, Gabe has to save himself. No matter the cost.
