Boundary: Castaway is a three-book spinoff of the Boundary series, co-authored by Ryk E. Spoor and Eric Flint. The series follows characters who become stranded on an alien planet and must survive using their wits and limited resources. Castaway Planet (2015) sets up the survival scenario, and the story continues through Castaway Odyssey (2016) and Castaway Resolution (2020).

The Castaway series shifts the Boundary universe from large-scale exploration to a more focused survival narrative. The three books track the castaways’ efforts to understand their new environment and find a way home.
