Sidereals comprise one of the most complex and interesting character types in the Exalted world, and this book delivers the goods very well. Unfortunately, you can't really tell, because the scan quality of this version is absoluetly dreadful. Given the quuality of the main rule book (which is original vector text instead of scanned pages), this is doubly dissapointing. Naturally, vector art is preferable, but the quality of these scans is bad even for a scanned book, and significantly worse than other scanned Exalted titles.
I give it two out of five, but only because the actual rules in the book are quite good.
