Sandy Morrison and the Pack of Pussies (Book 1)

Sandy Morrison had enough trouble trying to fit in at school while transitioning from her old life as Robert, and it's only with the help of her best friend Maggie that she gets invited to the hottest party of the year. But the invitation is a trick. Humiliated by the lead cheerleader Trisha, Sandy climbs a water tower and leaps...and then all hell breaks loose. Saving herself with a mysterious power, Sandy soon learns that she's a witch. But before she can adjust to the shock of being another kind of freak hidden in normal society, she is rocked by another stunning revelation: her best friend's family is a clan of werecats, and werecats and witches have been at war for over three hundred years...
