Erin has just realized that for the entirety of their life, their family has lied to them. Their Sight has been masked for years, so Erin thought the Pixies and Mermaids were hallucinations. Not only are the supernatural creatures they see daily real, but their grandmother is an Elf, meaning Erin isn't fully human. On top of that, the dreams Erin thought were nightmares are actually prophecies. While dealing with the anger they have over all of the lies, they are getting used to their new boyfriend, their boyfriend's bullying ex, and the fact that they come from a family of Demon Hunters. As Erin struggles through everything weighing on them, they uncover a Demon plot to take over the world. Erin just wants some time to work through it all on their own terms, but that's going to have to wait until after they help save the world.
