Blades of Ice by Faith Gibson

She’s a Gargoyle shifter. Archivist for her Clan. A female drowning in guilt.
Reeling from a traumatic event, Lydia Stone needs space from her overbearing but well-meaning family. When the opportunity arises, she jumps at the chance to investigate a clandestine group hunting for shifters. Traveling to the wilds of Alaska is daunting, but Lydia is a well-trained Gargoyle. Soon after arriving, she finds herself embroiled in a clan war that includes a type of shifter she didn’t know existed. Finding her fated mate at the middle of it all? He’s worth every mile of snow she must endure to get to him.

He’s a Polar Bear Shifter. Pilot for his family’s business. A male low on the totem pole.
Sawyer Beckett is used to being less than. In his pack, females are the leaders, and the males are good for few things. When his mother, Queen of their pack, goes missing, it’s Beck’s duty to find her. Before he can get to it, he meets a stunning female who claims he’s her fated mate. But she’s not a bear. Maybe that’s a good thing. Maybe he’ll be treated as an equal and not someone to merely do her bidding.
Lydia and Beck set out in the wilds of Alaska to track down the Queen, but things don’t go as planned, and Beck is abducted. Lydia must rely on both her Clan and a couple of new friends on her quest through snow and ice. Riddles and treachery abound, making it nearly impossible for Lydia to track down her mate. Will she find him before it’s too late?

The next generation is here. The kids from The Stone Society and The Hounds of Zeus MC series have grown up, and it’s their turn to protect humans while keeping their own existence hidden. And if they find their mates along the way? Even better. It isn’t necessary to have read the two original series, but you will find more of the characters’ back-stories there. While the Rebel books are written to stand alone, readers find them more enjoyable if read in order as there are minor spoilers.
