Welcome to The Celestial, where everything is an illusion. This ship is powered by magical servants, and its wealthy guests have a first-class ticket to enchanting amusements at sea.

Roe Damarcus, the heiress to the family responsible for The Celestial, has the power to summon spirits of the dead. Unfortunately, she has failed a trial to keep her magic. Now, Roe serves aboard the ship, where she might win the chance for a retrial if she outperforms other staff in a series of competitions devised for the guests' entertainment. But an infuriatingly handsome silks performer, Ivander, is hellbent on ensuring Roe doesn't win a retrial...

But Ivander isn't the only danger on board. Every night, the dream ship transforms into a violent nightmare, killing anyone who wanders the halls at night. Staff or guest, no one is safe in these waters.

At first, she was fighting for retrial. Now, she's fighting for survival and answers - for herself and her found family of staff... and Ivander. Roe investigates the ship's dark secrets, entangled with her family's history. Can she uncover the devastating truth before she, or someone she loves, becomes the ship's next victim?
