Another great addition to the Fighting Fantasy series.
Green is also keen to strike a balance between appealing to older and younger audiences. This doesn't suggest that he is unsure of who to aim the book at, but indicates his capability as a writer to craft a work so as to be of interest to a broad spectrum.
Overall, I would highly recommend Night of the Necromancer, well worth the purchase.
If you've had a go at the adventure yourself but you're getting a little bogged down, you can find a very concise solution here.
