When twenty-one-year-old Ivy Bishop wakes up in the hospital with no memory, she learns she was in a horrible accident. With no family or friends other than her neighbor Addison, she has to repair the broken pieces of her memory on her own.

One night, Ivy is awakened by two unexpected visitors claiming she is fae like them from a land called Archaic Hollow. Ivy believes them to be crazy but with the proof of magic and the demand of her blank memories, she decides to follow them to the fae realm in hopes to get the answers she seeks.

During her search, she learns there's a threat against Archaic Hollow. Someone is trying to unleash the Wild Hunt, an army of horsemen that was created to wipe out all mortals. But in order to set them free, one must break the four Iron Seals, a task that's impossible according to the royal family the VanAuclairs.

But Ivy is left to wonder, if that's true, then why do they seem worried?
