Wish You Dead - Rebecca Westcott

Mean Girls meets manifestation and murder... A contemporary teen thriller with a sapphic romance, perfect for fans of Heathers, Sue Wallman and Holly Jackson. Sixteen-year-old Morgana Merrick is all about control. She's the most feared, powerful and popular girl at Avalon Academy, while her half-brother, Art, and his chilled-out group of surfer friends reign peacefully in the year above, known for their legendary beach parties. At one such party, an ugly encounter with one of Art's friends leaves Morgana shaken. She retrieves the box under her bed filled with crystals, charm bags and her Book of Shadows, and asks the universe for justice to be served... As frenemy after frenemy wrongs or irritates her, Morgana manifests revenge upon them - and, to her surprise, it works. She feels invincible. Until someone ends up dead. Is the universe bending to Morgana's will? Or is someone else behind the attacks? And can she find out who it is, before anyone else meets a deadly end...?
