Adventurer Ethan Gage travels through the darkest and most superstitious realms of eighteenth century Europe, to the castles and caves of Bohemia to rescue his family and uncover a mysterious medieval device rumored to foretell the future. Having quick-wittedly survived the battle of Trafalgar, Ethan is rushing to rescue "Egyptian priestess" Astiza and son Harry from imprisonment by a ruthless mystic who seeks revenge for disfigurement, and an evil dwarf alchemist who experiments with the occult on Prague's Golden Lane. Using death as his ruse, and a pair of unlikely allies-a Jewish Napoleonic soldier and his sutler father-Ethan must decipher clues from Durendal, the sword of Roland. Astiza uses her own research to concoct an explosive escape and find a lost tomb, their tormentors in relentless pursuit.
