In the Valley of Flowers, Uren closes the blossoms before dark and takes down every polished thing that has begun to reflect the wrong sky. Then one flower refuses to close. A black Moon rises, three knocks travel from inside it, and a stranger falls to earth, putting out the stars wherever his feet come down. On Uren's wrist, her grandmother's backward-running clock unwinds three warnings, written in her own aged hand: Hide your name. Distrust the Road. And before dawn, erase the Moon. She does not know what the Moon truly is, or why her older self would beg her to unmake it - only that the world has come loose from its order, and something wearing her father's face is coming west. To reach dawn, Uren must unmake what holds the world together without becoming the next thing it obeys.
