Taming the Winter King by Ariel Hunter

An ancient curse binds them together, but it’s on Mara and Vareck to decide what the future will hold.

Mara traded one hell for another. Literally. On a desperate search to find Sadie, she followed a trail through a portal and into a hellscape where she feared how she’d find her sister. If she would find her at all . . .
She certainly didn’t expect to be taken by a band of savages and dropped at Sadie’s feet.

Vareck would his fated mate anywhere, even to another dimension. Reunited with Sadie and his wicked, good for nothing nephew, they’ve done what they set out to do.
There’s just one tiny little problem.
They’re trapped in a realm where the land is as inhospitable and unwelcoming as its locals. The only way to stay alive is to run or fight, and hope that they can buy enough time to find a way out before it’s too late.

Will Mara and Vareck be able to save themselves and pave the way to a brighter future for all of Faerie?
