Coyote shifter Bobbi Jo Simpson, top investigator for the Enforcer's Council, is finally closing in on the ultimate prize: The Chemist, who's been poisoning shifters all across the country for years. She's the best at what she does, so what could possibly go wrong? Try: just about everything. She's forced to partner up with the most stubborn, infuriating werewolf private investigator on the planet, who also happens to be her fated mate. Throw in a wily human thief who won't stop trying to help her, a surly lion shifter who may be the death of her, a computer genius who knows too much about her...if she survives this case, it'll be a miracle.Wolf shifter Jax Mackenzie has never been accused of being a nice guy – but being nice doesn't get the job done. A wolf without a pack, he works the most dangerous assignments doled out by a private security company – and his latest case is a real killer. A fatal Rage virus is spreading among the members of an elite BDSM club, and Jax is determined to get to the bottom of the case. To get what he wants, he'll ruthlessly use his supernatural strength, his wealthy connections, and Bobbi, the beautiful coyote shifter who's following him for reasons of her own. But the coyote is his fated mate – and possibly his mortal enemy. Now it's not just Jax's heart that's at risk – it's his life.
