the book has useful information and is quite detailed with its descriptions of the information. overall im happy with the content of the book. but i received my books as a gift brand new in the plastic and tashas cauldron of everything had a manufacturer defect on a page. i tried using wizards of the West coast official website to request a replacement as the store it was purchased from couldn't do anything but to no avail. their website is less than helpful and im still stuck with a book that has a manufacturer tear on page 105. luckily I can still read from context and use the information but its frustrating getting something brand new in the plastic with a manufacturer defect and getting told there's nothing that can be done
