Curse the Heart - The Harstone Legacy, #3

Sadie Goodwin is beginning to believe that there is a possibility that she might actually get the hang of all this witch stuff. She's accepted the prophecy that now guides her future and she has finally cast her first spell. Kind of. She should have known that things were going too smoothly. When a team of magisters arrive in Walker Bay to investigate the curse that almost took down a coven leader, Sadie is shocked to find that one of the team is familiar.
Not only does she have to hide her secret from somebody who knows her very well, she has to do it while trying to stop a plague that is sweeping through her new home, a plague that seems determined to destroy everyone.
