From the back of the book:
Deadly and mysterious flying discs hold the world in a grip of terror... the horn of a mythical beast casts a curse upon its owners... an ancient prophecy comes true, bringing death in its wake.
These are the perils at the heart of three Indiana Jones novels -- Indiana Jones and the Sky Pirates, Indiana Jones and the Peril at Delphi, and Indiana Jones and the Unicorn's Legacy -- and now you can relive the adventures. Between these covers you'll find all the characters from these stories, allies and enemies, ready to be dropped into your campaign; fascinating locations; new artifacts; and adventure hooks. Also included are two full-length adventures and tips on panning novels and movies for roleplaying gold.
