Amy Kathleen Ryan

Amy Kathleen Ryan is an American novelist known for the Sky Chasers trilogy, a young-adult science fiction series comprising Glow (2011), Spark (2012), and Flame (2014), which follows teenagers aboard a generation ship whose two colony vessels descend into rival factions during a decades-long voyage to a new world. The series combines survival adventure, questions of religion and governance, and a shipboard love triangle, and was optioned for film development. Ryan's other fiction includes contemporary young-adult novels published before her turn to science fiction. Public biographical detail beyond her bibliography is limited, but her catalog centers on character-driven speculative fiction for teen readers, exploring how isolated communities fracture and reorganize themselves under pressure, a theme she returns to across the trilogy's shifting points of view.
