When Tessa wakes up in hospital, she has no idea who she is or how she came to be there. The only clues are the ‘long, thin, striping slashes’ scarring her back. With no way of knowing who or where her family is, Tessa is sent to Cascade Falls College, an exclusive girls’ boarding school on the outskirts of Hobart. She befriends the ‘untouchables’, a group of quirky scholarship students, and joins them in their mission to dethrone Charlotte Lord, ‘the biggest princess this side of England’, and her perfect posse. However, there is a more serious battle raging beneath the schoolgirl rivalry, and students are beginning to disappear in mysterious circumstances. If Tessa is to save her friends, she must remember who she is before the full moon rises.
