This book can be downloaded and read in Apple Books on your Mac or iOS device.
Nix, Grace and Phoebe are having problems with their new elemental powers. They keep losing control and sooner or later they are going to get caught or hurt someone.
When Nix gets grounded from preforming a gig, after having a fight with her boyfriend and accidentally starting a small fire, the girls come up with a plan to practice their powers and regain some control.
Kendra, on the other hand, is shutting everyone out. Despite Phoebe's best efforts to get through to her, Kendra wants nothing to do with magic or Ivalice, but she can't hide away forever because Morgan is desperate to find a way to Earth and take back the elements. As he gets closer to a solution Morgan's obsession grows and begins to come at a cost.
