From the back of the book:
"Now you can experience all the thrills of playing the ADVANCED DUNGEONS & DRAGONS Game by yourself - in book form!
ADVANCED DUNGEONS & DRAGONS Adventure Gamebooks use a simple, unique role-playing game system based on the popular ADVANCED DUNGEONS & DRAGONS Game, incorporating two standard six-sided dice (not included), hit points, skill points, experience points, and much more.
In MASTER OF RAVENLOFT, you are Jeren Sureblade, a paladin who must face the terrors that lie within Castle Ravenloft and somehow destroy the evil, undead Count Strahd von Zarovich - the Prince of Vampires himself!
ADVANCED DUNGEONS & DRAGONS Adventure Gamebooks read like books, play like games, and offer a thrill minute - with YOU as the hero!
Unique tear-out Character Stats Card included!"
