Shifting Hearts by Romy Lockhart

Rachel is stunned when she finds out she has to go to a mysterious elite academy. A powerful witch, she should have expected her fate would be separate from that of her quarter witch best friend. Cheryl has accepted they’re going to part, so she resigns herself to doing the same.
When she discovers the true nature of her escort to her new home, she becomes trapped in a situation that quickly turns deadly. Her determination to survive is the only thing that keeps her from sinking into despair.
She doesn’t expect to be rescued by shifters, and she definitely doesn’t expect to find out they’re her mates.
Fate brought them together. Will it tear them apart?
