Having glanced through the book I became unsure of of the credentials of the persona within. Seeing descriptions like "the first feminist" and references to alchemy made me feel uneasy. The Czar Nickolas listed as a saint also caught me as slightly odd. Looking at the back cover I see that the author has also written book(s) on witches and witchcraft. I personally don't think one can be true to both genres. Look elsewhere for a book of saints.
