I'm new to this forum and new to sudoku. I'm comfortable doing easy puzzles, and now I want to try to do medium to hard. I want to buy a spiral bound medium to hard book, but I cant find one. I looked on amazon, and I found one, but the book was only 6 inches long and i'm looking for something about 9 inches. Basically one puzzle to a page. With that being said does anyone no where I could buy those books. I would really appreciate your input.
Thanks
