Witches of Hogsback [EPUB ebook] 

Zelda is a self-proclaimed do-gooder and cannot stay quiet if she sees something wrong. Unfortunately, this doesn’t win her any popularity contests – and now not even her ex-boyfriend, Dylan, wants to put up with her anymore. Desperate to escape from everything for a while, Zelda signs up for the school’s hiking trip to Hogsback. Her illusion of having a nice, relaxing time shatters when she stumbles upon a mystery nobody else wants to solve: the death of local teen Stephan Dale. Quickly, she is neck-deep in trouble: from having her room vandalised to nearly being killed. Someone clearly doesn’t want her solving Stephan’s death. Her prime suspects are the group of teenagers known as the ‘witches of Hogsback’, but are they really witches? There is more to this case than meets the eye.
