Sins of Leo by Eve Langlais

This warrior can’t let go of the past.

Leo’s life is a living hell. He lost his wife and baby to a monster and blames himself. He’s spent years trying to overcome the guilt, but it turns out heavy drinking isn’t a solution. When the boss of the Zodiac Warriors orders him to seek help, he ends up spilling his guts in a shrink’s office. However, the attractive woman isn’t falling for his pity party—and knows he’s hiding something.
When her newest patient arrives for his session, Dr. Ruth Warmstone hopes her couch survives the massive, muscled man that flops atop it. It isn’t just his body that’s heavy but his dark thoughts. Right away, she knows he’s holding back. How can she get him to open up?
Maybe she’ll get a chance to unlock his secrets when he helps her to evade capture by an organization that wants something she inherited from her archeologist father. While on the run—that turns into a quest to discover her father’s last known whereabouts—she discovers Leo is no ordinary man. He’s a Zodiac Warrior with a mission from the stars.

Together, they must explore a jungle in search of an ancient artifact and find a way for Leo to forgive the sins of his past so love can flourish in his future.
