Shepard embraced many different themes throughout his career. In his early work, he wrote extensively about Central America. This included clearly science-fictional stories about near future high-tech jungle war (such as "R&R" and "Salvador"), as well as stories that seemed more in line with magic realism. Many of these, such as "Black Coral" (which concerns an American living on an island off of Honduras) and "The Jaguar Hunter" (the story of a man whose wife's debt forces him to hunt a mythical black jaguar, which his people consider sacred), explore cultural clashes. Shepard traveled extensively in Central America and lived there for a time.
