To Wed a Werewolf — Kryssie Fortune

Sylvie's more human librarian than half-blood Fae princess and she definitely prefers books to men. Then, she learns her unwanted Lykae fiancée is marrying someone else. If she doesn't stop the wedding, the Fae will resume the border war with the Werewolf nation. A high-handed Lykae security guard blocks her every move, and when her plans go awry, she's kidnapped, stripped, and bound for his pleasure.

Caleb the Cold, King of the Lykae, will do anything to make his younger brother's wedding special--even pretend he's a security guard and kidnap his brother's former fiancée. Punishing her is pure pleasure, until he realizes she's his mate. Now he needs to woo the woman he's tormented to the edge of madness, but is it too late to claim her heart, and make her his?
