A good start to the Sorcery series, the best and most in-depth solo gamebook series by far. Magic system adds depth, and penalties for not eating and sleeping add realism. John Blanche's illustrations are amazing. ( )

An increadable series: Most fantasy gamebooks like this don't quite reach this level. I wouldn't give most of the Fighting Fantasy series any more than four stars, to tell you the truth. Not because they're poorly written, far from it, but just because they're nowhere near as involving as the other gamebooks. The Lone Wolf series springs to mind.
But still, this series blows the rest right out of the water. Unlike Lone Wolf, and rather more like the Grecian Chronicles, this has a single continual storyline that forms the overall point of the series.
It's very well written. There's an increadable amount of depth to just about everything, you get to find out more about all the characters, locations, and so on. If you like interactive fantasy, give this a shot or you'll be missing out.
