Initially I was a bit unsure about reading these books as they weren't centered around the Lakeside Courtyard and all the characters I'd grown to love so much. But, in the end I loved the world this author created too much to not read them. And I knew that I would love the spin-off books as well.
I said "love" a lot in that paragraph, didn't I?
Anyway, this book definitely does not stand alone, in my opinion. You'd need to read the preceding books (the ones centered in the Lakeside Courtyard) in order to fully understand the world and events referred to in this book.
