Home (the portal series, book 3 ) is an alternative history adventure book. A masterpiece, Richard Bowler’s work on this is spectacular. In this epic coming of age sequel to TERRA, earthborn Larry Barnes discovers his ability to move through the multiverse via a portal of his own creation. A powerful and dangerous ability, Larry seeks the council of a priest named Affron, who has the same ability but when Larry discovers affron has disappeared from TERRA, he risks following him to Elysium leaving his friend pasta behind.
