In 1979, Edward Packard, who is easily the best author of the entire gargantuan Choose-Your-Own-Adventure series, wrote and published this book, and with that one stroke he not only gave us all a classic adventure story but founded an entire new genre of fiction as well! The whole idea of the "interactive novel" did not even exist before the first Choose-Your-Own-Adventure, as far as I know. The instant the series became popular, almost thousands of imitators started up, most of which died while the series that was started by "The Cave of Time" just kept going and going, like the Energizer Bunny. Today, it is considered just part of a whole category of books. "The Cave of Time" itself is an imaginative story that takes its reader all through time, from the end of the entire universe to the days of Camelot and everything in between. The mechanism for the time travel is NOT the typical machine, but rather a system of tunnels that can transport you in different directions through time depending on which way the tunnel is heading. An original and intriguing idea. Since the early '90s, the CYOA series has sadly gone downhill, with practically all the books being about martial arts and sports--as if they suddenly think that little GIRLS never read their books! and the number of endings has shrunk and shrunk, until now it is often less than TEN per book! As a female who has been reading, collecting, and loving this series since she was 8, this is a major disappointment for me, and I'm sure it would be to anyone else out there who may remember the "good old days" of this series. But THIS book, with its subject matter that would appeal to ANYONE, both boys AND girls, and its whopping 40 endings, is the classic that started it all. This is the standard that interactive fiction for kids has been trying--and failing--to reach ever since. ...Notorious
