All her life, 16-year-old WREN has lived in a mining colony on an isolated planet. She longs to be a resource-gatherer like her father, RADDICK. With him, she gets to venture outside the claustrophobic colony into a thrillingly wild natural world. But the colony’s resources are running out, and Wren’s mother — an elite scientist — plans to move the colony to a different planet. That’s when Wren finds MEMOIRE, a mysterious orb that triggers visions of a terrible future if her mother’s plans are allowed to succeed. With the help of Memoire and her friends, Wren will have to find a way to save her home and community.
