Fantasy, Young Adult || Finn has escaped Incarceron, but Keiro and Attia are still Inside. Outside, things are not at all what Finn expected - and both Finn's and Claudia's very lives hang on Finn convincing the Court that he is the lost prince. Back Inside, Keiro and Attia are on the hunt for Sapphique's glove, which legend says he used to escape. In order to find it, they must battle the prison itself. Incarceron has built itself a body and it wants to go Outside - just like Sapphique, the only prisoner Incarceron ever loved.
