This is an X-Men choose your own adventure book. It's pretty neat...this came out in the days before the X-Men were a household name and there were few toys and video games. This was about as close as you could get to being the X-Men. The book is a relatively hard one...if you don't cheat, you'll have to do it several times...probably. It has a good chunk of the X-Men villains from the time in it...like the Brotherhood of Evil Mutants, the Sentinals, and the Hand. If you're an X-fan, you can't be without this little nostalgic nugget.
