Indiana Jones and the Dance of the Giants is a 277 page novel written in 1991 by Rob Mac Gregor and published by Bantum Books.
Back Cover reads: Indiana Jones has landed his first teaching post, in the archaeology department at London University. His brightest and prettiest student is a twenty-year-old Scottish girl, Deirdre Campbell, who claims she's uncovered a golden scroll, proof of the true existence of Merlin, sorcerer of myth and legend. Indy's intrigued by the thesis and by Deirdre. So, too, is member of Parliament Adrian Powell. He's seeking to resurrect the ancient order of the Druids, whos secrets of power could pave his way to world conquest. But first he needs the scroll ... and he is willing to kill to get it.
Where there's magic, mystery, and murder, Indy goes to the head of the class. Dropping his books and picking up his bullwhip, he joins Deirdra on an action packed chase across Britain, from the peril-filled caves of Scotland to the savage dance of the giants at Stonehenge -- where Merlin's secret will finally be revealed. But not before Indy gets a lesson in love from Deirdre ... and a lesson in hate from a maniac who means to rule the world.
