Written and illustrated by Manuele Fior 272 pages; hard cover; full color The Great Invasion originated from the sea. It moved north across the mainland. Many fled, while some took refuge on a small concrete island called Celestia, built over a thousand years ago. Now cut off from the mainland, Celestia has become an outpost for criminals and other misfits, as well as a refuge for a group of young telepaths.
