This book is filled with amazing artwork and lots of fun facts about H.P. Lovecraft's well-loved (and feared) mythos creatures. While the book stands on it's own for those who are only interested in the Cthulhu Mythos, it's also a well-made book for those running Call of Cthulhu games.
Overall I'm very pleased with the PDF version of this book. It's everything I hoped for, times ten.
