Werewolf PI Dylan Weems is a hired to solve the murder of a client’s customer. As an ex-cop, Dylan is the perfect man for the job, but he doesn’t expect the complication of alluring fox shifter Rey. Ever since finding the dead body of one of his clients, Rey Mercier’s life is a mess, and he needs help desperately. He has no idea why he’s the target of some ruthless people or what he did to anger them. Hopefully Dylan and his motley crew of shifters at Apex Investigations can help him find out, but first Dylan and Rey have to deal with literal corporate tigers and dire crocodiles shifters… all while deciding what to do about the mate bond that’s becoming undeniable. And is that even possible between fox and wolf?

A client with a cheating wife, a warehouse of cult members, and someone with a deadly vendetta—just a day’s work for Apex Investigations. Or is it? Bear shifter “Grizz” Locke is ex-military and ready for PI work, which if not exactly safe seems less likely to get him killed on a daily basis. The added bonus of teaming up with former lover, Brock, a jaguar shifter, is all the incentive Grizz needs. Brock can be a grumpy kitty, but has found a home and family at Apex. And now as luck would have it, he has a chance to rekindle his romance with Grizz. They might even rebuild their mate bond, severed years ago—as long as they don't manage to get killed first. When an enemy targets the Apex team, Brock and Locke will fight with all they have to protect their own. To enjoy life and love as fate intended, they will have to find out who wants them dead before someone at the agency pays the ultimate price.

Wolf shifter PI Mick Hartness is sick to death of being on the bad side of a criminal who wants him and his while team dead. Now, with the help of the cops and the feds, Apex Investigations Inc. is closer than ever to reeling the guy in and getting back to living life without hiding. But that means Mick needs all of his mixed pack on deck and ready to fight, including their youngest member, bear shifter Kit, who Mick has the softest spot for. Kit is sure his skills can help not only catch their nemesis, but help take some of the stress of running the agency off Mick. Too bad Mick will never see him as anything as a kid who needs to be protected. Which is why Kit decides to strike out on his own and get a job that allows him to do more than take pictures of cheating husbands and keep the motor pool running. The thought of losing Kit finally makes Mick ready to show Kit how he really feels; that kit his mate. Can he keep Kit with him and also catch a killer who's becoming more and more dangerous everyday? Or will Mick lose everything he holds dear?
