An Omegas Power

Katie has had enough. She's finally gotten enough courage and strength to leave the pack that has treated her like a slave for years. She doesnt really care what happens to her now, anything is better than the life she had been living. Just when she finds a pack that treats her the way she should be treated her old pack comes back to haunt her. And what's this about her new Alpha saying she's an Omega, and that Omegas have powers? This is all so hard to believe. To top it off she's found two mates in this new pack. But with her old pack coming after her will her new pack and mates be able to protect her?
