Elior of Lempara, the crown prince of fae folk, wakes on the ground and realizes he's in the human realm-and has no idea how he got there. He remembers his father pointing his staff and a blinding light, but other than that, nothing. Elior needs a portal home, but where is the portal? For the time being, it looks like Elior is stuck in Brooklyn.
When mercenaries come after him, the prince becomes entangled with an unsuspecting changeling. Elior and Alex put their heads together to find a portal back to the fae realm and evade the dangerous trio hunting them.
However, it's difficult navigating an unfamiliar world where Elior does not belong. He seeks a human with knowledge of the supernatural, and despite Elior's protests over dark magic, the pair settle for a witch. Before he finds the portal back, Elior must decide: is he the person he was before losing his memory or has the human realm changed him into someone else?
