Steampunk Slug: the Slimy Scientist

Steampunk Slug is an ongoing series of science fiction novels revolving around the adventures of the titular slug scientist. The Slimy Scientist, or simply The Scientist, travels between dimensions in his giant snail shell ship, the Epoch, helping those in need along the way. He is often accompanied by one or more less-educated companions.

Created by author Aislinn Queshire, the series is long-running and has changed hands many times over its run, a new author usually tackling 3-4 books before passing the series to the next author to continue the saga. Milla Kramer, Fan Brightgrass and Caddi Prosser are some known fans of the series.
