Wish You Dead

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...?
