The Expedition Inc series by John Wilker currently consists of two books: Island of Secrets (2020) and Terminal Danger (2023). The series takes a different direction from Wilker’s space opera work, focusing on Earth-bound adventures and investigations.
These books show Wilker branching out from the science fiction that made up his earlier catalog. The Expedition Inc stories trade alien worlds for terrestrial danger, though they keep the action-heavy pacing that characterizes his Space Rogues books.
