Trying to discover time travel, absent-minded genius Dr. Marvin Brewster accidentally transports himself to a parallel universe where magic really works … a land that resembles medieval England, but is populated by leprechauns, virgin-hating unicorns, coffee drinking beatnik vampire elves, rapping Rastafarian grunge dwarves, philosophically musing dragons, ambulatory vegetation, bumbling outlaws, gorgeous brigand queens, cursed were-princes and evil wizards. In a world where science is unknown, Brewster’s knowledge results in his being mistaken for a sorcerer … but the real sorcerers have a powerful, exclusive guild, and Brewster’s not a member. As he searches for his missing time machine, Brewster sees no harm in the locals thinking he’s a wizard, but the Grand Director of the Sorcerer’s Guild is out to find this interloper and learn the secret of the strange device that he arrived in…. less

Trapped in a parallel universe, reluctant sorcerer Marvin Brewster must stop an evil wizard who has captured a time machine.

Trapped in a paralled universe, Dr. Marvin Brewster marshals his renegade nation of brigands, dragons, trolls, vampire elves, and the runesword Dwarfkabob to challenge evil wizard Warrick. Aware that he's the dastardly villain of a nonstop rollicking adventure romp, Warrick plays the role of destiny and changes the path of the ambivalent magician--while it's being written.
