In the floating world of Erathia, where kingdoms float on clouds, time is traded like gold, and books tell truths heard only by their readers, Lyanna is thrown off the edge of all she knows. On her eighteenth birthday, she is accused of stealing Time Seeds—mysterious artifacts that prevent islands from disappearing into the void. Her punishment: to be dropped from her cloud island… for seven days. But time never flows in Erathia. During her descent, Lyanna meets Caleb, a rogue cloud hunter with a golden net and a hidden past, and hears a voice in the wind urging her to find "the prisoner in the last cloud tower." What she discovers there will reveal not only her own fate but the fate of time itself. Inside a tower built of forgotten dreams, guarded by nightmarish thoughts, lives Silas—a man with amnesia whose eyes reflect worlds that no longer exist. Together, they embark on a journey through time-torn markets, sentient libraries, and islands disappearing in reverse, uncovering ancient truths behind the Broken Moon and the return of a reality-devouring force known only as "The Shaper." But to mend time, Lyanna must make a crucial decision: restore the past—or protect the future? Free Silas's memory—or keep the doors to the Forgotten Realms closed forever? In the end, the only way forward may be to step outside of time altogether.
