Following a shocking turn of events, Serilda finds herself ensnared in a deadly game of make-believe with the Erlking, who is determined to propel her deeper into the castle’s lies. Meanwhile, Serilda is determined to work with Gild to help him solve the mystery of his forgotten name and past.

But soon it becomes clear that the Erlking doesn’t only want to use Serilda to bring back his one true love. He also seeks vengeance against the seven gods who have long trapped the Dark Ones behind the veil. If the Erlking succeeds, it could change the mortal realm forever.

Can Serilda find a way to use her storytelling gifts for good—once and for all? And can Serilda and Gild break the spells that tether their spirits to the castle before the Endless Moon finds them truly cursed?
