A teen endeavors to find his missing father and sister in this fantasy epic by Dyson, set in a technologically advanced world where mystical airborne particles called spryts can sometimes endow humans with powers of creation or destruction. Along with their mother, 15-year-old Gai and his 12-year-old sister Lynd live on Hop, a "floating port amid the unforgiving sea" made of deteriorating wood planks and various detritus. Ever since their father boarded a ship off Hop and disappeared five years ago, Gai, who has the power to fix anything, has worked tirelessly to help Lynd hone her destructive gifts. Hop citizens are warned not to venture out after dark, especially when spryts are out full force, as the secrets surrounding their oft- dangerous power are still unknown. But when Lynd suddenly disappears, Gai sets out to find her, all while uncovering the truth behind the spryts and the world beyond Hop. What unfolds is a multiple timeline- and dimension-hopping adventure across a universe on the brink of a technological war between the forces of creation and destruction. At the center of this imaginative volume is the siblings' affectionate relationship, which grounds the action-packed plot. Most characters are coded as white. Ages 13—17.
