Moon Cursed - Shifting Magick Trilogy, #1

Olivia Kelly is cursed. The eldest of three witches, she is doomed to spend her existence alone unless she finds and mates with a male descendant of the moon goddess, Artemis. Just when she thinks that all hope is lost, a handsome - and very naked - Alpha wolf stumbles into her life. Sawyer Scott has been spelled to turn into a house cat once a month during the full moon. A humiliating predicament for an Alpha, and one that has kept him from his Pack every full moon for the last year as he searched for the witch responsible.
In a last ditch effort to find the crazy old lady; he stumbles upon a scent he can't deny. His mate.
