Finn has escaped from the terrible living Prison of Incarceron, but its memory torments him, because his brother Keiro is still inside. Outside, Claudia insists he must be king, but Finn doubts even his own identity. Is he the lost prince Giles? Or are his memories no more than another construct of his imprisonment? And can you be free if your friends are still captive? Can you be free if your world is frozen in time? Can you be free if you don't even know who you are? Inside Incarceron, has the crazy sorcerer Rix really found the Glove of Sapphique, the only man the Prison ever loved. Sapphique, whose image fires Incarceron with the desire to escape its own nature. If Keiro steals the glove, will he bring destruction to the world? Inside. Outside. All seeking freedom. Like Sapphique.
Imagine a living prison so vast that it contains corridors and forests, cities and seas. Imagine a prisoner with no memory, who is sure he came from Outside, even though the prison has been sealed for centuries and only one man, half real, half legend, has ever escaped. Imagine a girl in a manor house in a society where time has been forbidden, where everyone is held in a seventeenth century world run by computers, doomed to an arranged marriage that appals her, tangled in an assassination plot she both dreads and desires. One inside, one outside. But both imprisoned. Imagine a war that has hollowed the moon, seven skullrings that contain souls, a flying ship and a wall at the world's end. Imagine the unimaginable. Imagine Incarceron.
