Once upon a time, in a land far, far away (Los Angeles)… When Cedric, crowned prince of Caelum, and his fellow royal friends (including his betrothed, Kat) find themselves stranded in modern-day L.A. via a magical portal and an evil traitor named Malquin, all they want to do is get home to Caelum—soon. Then they meet Liv, a filmmaker foster girl who just wants to get out of the system and on with her life. As she and Cedric bond, they’ll discover that she’s more connected to his world than they ever could’ve imagined…and that finding home is no easy task…

The adventures of three teen royals and foster girl Liv, which began in The Marked Girl, conclude in this exciting sequel. In the fantasy world of Caelum, Liv, Cedric, and Kat must attempt to defeat an evil traitor and his army to save their families and the kingdom. But the city they left behind is facing its own problems: back in Los Angeles, the sky is orange, gravity isn’t working right, and earthquakes shake the ground every few hours. Opening the portals has had devastating effects, and Liv’s best friend Shannon and Cedric’s frenemy Merek are the only ones who know what’s going on – and that tracking down the murderous Knights of Valere might be the way to fix everything. It's a race against time as the crew must find a way to reunite and combine their quests to save both worlds.
