3.5/5 stars
This is a collection of short stories, poems, authorial anecdotes, illustrations, and even a recipe. I enjoyed some of the short stories, hearing about what ancient artifacts MWT based things off in the books, and little glimpses of life before, during, and after the main series.

However, I felt like this has raised more questions than it gave answers, and of the answers it did give (or hint at) I found myself somewhat frustrated about.
I think my expectation of this book was a little off, as I was expecting more answers and short stories, but this is much more a collection of drabbles and ideas about the series that is very ambivalent.
