The Copernicus Legacy is a bestselling series written by Tony Abbott. It is about the adventures of Wade Kaplan, Darrell Kaplan, Lily, Rebecca Moore, and Roald Kaplan, to try to destroy a time machine made by Ptolemy, but discovered and used by Nicolaus Copernicus, from the dangerous Teutonic Order of Ancient Prussia. It currently has three books in the series, but one is in a series diverted from The Copernicus Legacy called Copernicus Archives. While a work of fiction, it does incorporate some facts about Copernicus's history.
