This is a compilation of all the books in the Chronicles series, covering about 1.300 pages. But don't worry, it easily read! In the book, there are notes from the authors, commenting the current text, whether why someone got their names, or how certain events happened. However, these notes can be contain spoilers (or be jibberish for those not knowing the world of Krynn), so I would only recommend the book for those that already read the original books.
The only reason I only rate it with four stars is because of the spoilers in the notes.
