This book is not only a great supplement for Call of Cthulhu, but also an incredibly informative book with regards to history I never learned. The character creation section is robust and handy for creating dynamic characters. The Storytelling section is fantastic, addressing a lot of concerns which players/keepers may or may not voice about how to properly use the information presented.

Not only is this book filled to the brim with information, but the associated handouts are well done and always appreciated as a Keeper.
