Coming Up Aces E-BOOK

He's a Gryphon shifter biker who hunts down cult members.  She's a King Cheetah shifter and FBI agent who tries to make the world a better place.  

Asher "Ace" McMurray spends his time going after The Ministry, a cult responsible for the near apocalypse thirty years ago.  His beast has never been interested in anyone he's dated. That changes the moment he meets a female within the walls of Haven, one of The Ministry's compounds. He recognizes her as another predator, and he's determined to find out what kind. One conversation convinces them both she's in trouble, so Ace offers his home as a safe house.

FBI Special Agent Rayna Bellamy was sent undercover in a cult for reasons that didn't make sense. When her chance to leave Haven arises after four months, she takes it, but things aren't as they were when she left. GIA Agent David Spencer had been arrested for kidnapping his adult daughter, Rhiannon. Spencer turned informant, feeding Rayna and her boss intel about the cult as well as the Hounds of Zeus MC. Now, though, he is no longer in custody, and Rayna doesn't know who to trust. Enter a broody biker Rayna was led to believe was a mercenary, not the kindhearted male who gives her sanctuary.

With Spencer in the wind, Rhiannon is once again in danger, but David isn't the only one looking to capture the female. Ace and Rayna make it their mission to protect Rhiannon while dodging rogue FBI agents.

Coming Up Aces is written as a standalone, but many readers prefer to read the series in order as it will contain spoilers to previous books in the series. Ryker Lazlo and his mate, Rhiannon, from Book 3, Starting a Ryot, play a significant role in this book.
