The Warlock Unlocked (Warlock of Gramarye) ([warlock Series])

A scientist from Earth at heart, Rod Gallowglass has come to terms with the "magic" of Gramarye, and is just beginning to understand his own powers. *** But when his family accidentally goes through a portal to what appears to be an alternate universe, he must follow them into a world where magic really does seem to work and where the laws of the universe seem to have been rewritten. *** Bringing his renowned blend of science fiction and fantasy back to the world of Gramarye, Christopher Stasheff once again redefines what is real and what is "magic." ***
