The Alpha Witches Trilogy. Alpha Witches, #4

The volume contains all three installments in the Alpha Witches Series! A Witch for the Werewolves: 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.  The Witch and the Kraken: The wolf pack has been freed from its curse, but now the witch Ali and her coven must face a new threat. Something is stirring in the waters of a parallel dimension, and its power threatens to rip the veil separating the mundane world from the supernatural. Whatever the beast is, it is stronger than the coven and wolf pack combined.
Ali has one chance to confront it and heal the rift, but will her sacrifice be enough to prevent catastrophe? A Witch for the Dragons: After helping save a werewolf pack and a pod of krakens, the witch Ashlin is ready to return to her own world. But before her coven has time to congratulate themselves on a job well done, a terrifying roar echoes through the sky. It is the sound of a dragon, and it seems most unfriendly.
Ashlin travels to a scorched island where she finds the situation is even worse than she feared. She's willing to go to any length to protect her coven and their friends, but will her sacrifice be enough to satisfy the monsters before they burn the world to ash?
