Sonic, Knuckles, and Tails reunite against a powerful new adversary, Shadow, a mysterious villain with powers unlike anything they have faced before. With their abilities outmatched in every way, Team Sonic must seek out an unlikely alliance in hopes of stopping Shadow and protecting the planet.

The multigenerational epic follows two concurrent time periods: One, the story of young Eli McCullough after he is kidnapped and indoctrinated into a tribe of Comanches in 1849. The other, 60 years later, when we see a grown Eli struggle to maintain his family’s cattle empire during the turbulent Bandit Wars of South Texas. Based on Philipp Meyer’s acclaimed novel.
