A Witch for the Wolves - Alpha Witches, #1

Lisa is a shy girl with hopes of joining the Kappa Alpha Sorority at her college. Her initiation includes a naked run through the woods, but instead of returning to the cabin they've rented, Lisa finds herself thrust into a supernatural world full of strange creatures. She's confronted by a pack of werewolves, and learns that they are under a curse. But saving them requires a sacrifice that this virgin isn't sure she can bear to make.
