Query: I LOVE THIS BOOK!

I recently started working crossword puzzles, and was looking for a book that I could use when I could no longer do it on my own. I bought two books, but I use this one all the time. It has a lot of words/details. I bought the hard-cover and decided to buy the paperback to carry around in my bag. Little did I know the paperback is as big and as thick as the hard-cover!I would recommend this book to anybody who is into crossword puzzles!
