"The Hidden World" is the concluding volume in Paul Park's remarkable tale of Roumania, a world that is both more real and yet also more mysterious and magical than our own.After finding out that she is the lost princess of Roumania and the mythical White Tyger, Miranda's fate is still uncertain. The ghosts of her enemies cluster about her, the insane spirit of the Baroness takes possession of her body for a time, and demons released by her mother are abroad. And through it all her heart calls out to Peter, away with the army, whom she has come to love, and her best friend Andromeda, sworn to help her and protect her. There are no easy answers; it all looks impossible. Any hope may lie in the hidden world of spirits, where death is but an inconvenience.
