Shadowdoom is a medieval-set fictional chapter book, and is the ninth volume of Dark Realms series and is one of the book series that Greg wanted to read. Due to its length and lack of pictures, Greg enthusiastically shares this book with others at the "Reading is Fun" book club, but it was rejected by Susan, who deemed the book cover as offensive to women, because of the illustration's suggestiveness. Greg later comments that the book cover had nothing to do with the story, as there were no women in the book at all.
