Shadow Girl by Kate Ristau
Áine lives in the light, but she is haunted by darkness, and when her fey powers blaze out of control, she escapes into the Shadowlands. But she cannot outrun her past. Fire fey and a rising darkness threaten the light, burning a path across the veil. Her fiery dreams come to life, and with the help of Hennessy, an uninhibited Irish girl, Áine dives into the flames to discover who she truly is. Her mother burned to keep her secret safe, and now Áine wields the deadly Eta. She must learn to fight in the shadows — or die in the flames.
This is not a fairy tale.
