I suddenly decided that I like the Discworld novels right after the author passed away. In fact, I was in the middle of reading Guards! Guards! when I got the news. I feel a bit guilty because of it. 
 There are a lot of guides out there about which order to read the Discworld novels in. This is the first book chronologically, but it is in a slightly different vein to the rest of the series. This book basically takes a traditional fantasy story and makes fun of it. That's about all it does. It doesn't go much deeper. It doesn't give too many indications of the depth to which Terry Pratchett satires, primarily, English life. 
 I personally enjoy light-hearted romps, and had no issues at all with the lack of any message being sent across in this novel. Or I'm too dumb to find one. Either way, what this book does provide is a glimpse into the mastery of Terry Pratchett's prose. Good lord, the man can do funny like no other. 
 I absolutely loved it from start to finish and think it's the best thing since sliced bread. If you like his style of writing, then you will like all of the Discworld books, and this is a great book to start on. If you don't like his style, then you won't like any of the series. Pretty simple. 
 To me, this is a must read book. I am aware it's not everyone's favourite in the Discworld series, but I recommend it!
