And where a robot named Mach is, in turn, swept away to a world of bizarre and terrifying wonders: the dazzling world of Phaze…

"A little adventure, a little romance, a little gentle humor and much philosophical speculation… Anthony is as facile as he is prolific. He creates and populates realms with fanciful creatures from mythology (unicorns and werewolves), fairy tales (ogres and trolls) and his own imagination." -Cincinnati Post
"A tale of adventure and intrigue featuring unicorns, evil wizards, extraterrestrials, and political tyrants, as well as two engagingly naive protagonists… Highly recommended!" -Library Journal
"Don't underestimate Anthony's popularity!" -Kirkus
"A complex tale of transposed identities, cyborgs and robots, werewolves and golems...!"-Publishers Weekly
"The versatile and prolific author of fantasy and science fiction returns to one of his most popular series I with a tale of adventure and intrigue!"-Library Journal
