The Mating Frenzy by Bonnie Vanak

Strong-willed, curvy Ella Princeton doesn’t have time for dating or dreams of fantasy. Practical to the core, she’s working three jobs to support her family. But everything changes when Ella meets a handsome naked man while searching for a lost cat.
Exuding male strength and pure sex, he makes her heart race and her hormones fire. She wants to crawl all over him and lick him from head to toe. Too bad he’s crazy and talks as if he’s a shapeshifter from another world where the sharp snows of winter hold power and magick.
Kieran of the Winter Kingdom may be a tomcat when it comes to sex, but he is equally smitten with Ella, his new assignment. He must convince fiery, lovely Ella that she is a werewolf, and coax her into joining him on a quest to find a rare crystal.
The hidden gem will turn her into a powerful warrior to fight the gathering darkness in the world. Only Ella can help stop a growing threat to Xavier, the Crystal Wizard, and save him and perhaps the entire human race…
