Eighteen-year-old Isla lives in Naudiz, a historical reenactment community in a future America. Contracted by the government to perform the traditions of her Mennonite ancestors for tourists, she loves her family but wonders where life could take her.
A new schoolteacher spots Isla's potential as a CREIA cadet, making her one of many girls recruited to visit the closely guarded Library of Ages. There are rumors that girls who go to the CREIA never return, but Isla is armed with a powerful tincture from her brother's workshop and has her best friend Esme by her side.
She soon learns the dark secrets hidden in the CREIA's beautiful campus. The girls are assessed for a sinister destiny and forced to become dream addicts, forever lost in a hallucinogenic reality. When it seems there is no hope left, Isla's connection to nature and the chance at a new love reveal that the key to the future lies in the past. Sifting among the ruins, she finds herself standing up to answer the question all Citizens want to know: Where will they go as the Earth begins to heal from environmental destruction, growing into a lush land full of promise?
