Review from Amazon:
Now most FF Gamebooks are set on the magical world of Titan, and if not they're generally set in the future or some other science-fiction setting.
This one however is neither. It's set in the present day where a superhero fights crime in a large United States city. And this brave defender of millions of innocent citizens...is YOU. (However it's clear Steve Jackson's still into Titan because he set this story in "Titan" City and later one has the opportunity to purchase "The Warlock of Firetop Mt"!)
Basically this adventure is a superhero adventure. And a very good one at that too!
When you were born, it was an anxious moment because your parents were part of an American top-secret genetics project. Intended to enhance untapped human superpowers, and you were the result. However the success of the experiment (i.e. your powers) are so secret even the other members of the project don't know about them. And to this day you thwart criminals and stand up for human justice behind a mask. Going under the alias, the Silver Crusader.
But now The Crusaders' biggest challenge has arrived. F.E.A.R. - the Federation of Euro-American Rebels is launching a campaign to take over the western world, starting with your home town! With the aid of grasses, scattered clues and captured criminals eager for plea-bargaining, you only have a few days left to stop them.
N.B. I wasn't quite accurate earlier when I said set in the present-day, the cold war between West v East is still here.
So if...er...WHEN you succeed you can truly say you saved the world from FEAR itself!
Notice I haven't specified what kind of powers the Crusader has? That's because it's YOUR choice, that's another beauty of Steve Jackson, one of many clever brainchilds. I won't tell you exactly what, but you can basically choose any kind of superhero trait you can think of.
