Heart of Ice (BDSM Fantasy Romance) (A Not Quite Wicked Tale) by Brynn Paulin

Kai is perfectly unhappy with his life. Cast into a role as shop boy and forced into marriage to save his family, he sees nothing good in his future. In fact, his betrothed, Gerda, seems to hate everything he enjoys. Especially winter and his attraction to dominating his partners. His prospects look grim…until the Snow Queen arrives.

Wyn has spent her life alone, living vicariously through those who love winter. When she learns of Kai's predicament, she knows she must save him. If only she could save herself. She craves his dominance, but there's one tiny thing standing in their way. No human can touch her without experiencing chilly agony. And that might bring any relationship to an icy death.
