This book is exactly what it says it is: a collection of rituals for use with M20: Sorcerer. One of the problems that the Sorcerer books have always had is a lack of rituals, and though M20: Sorcerer mitigates this to an extent, there simply isn't enough variety of rituals for players who aren't interested in coming up with their own. This book helps a lot, including rituals for all the Paths in M20: Sorcerer. They're generally good (though there are a couple that seem borderline but that's inevitable with a large number of items like this and the flexibility of WoD's, and Mage in particular's, rules).

Strongly recommended for anyone looking to run or play M20: Sorcerer
