wish i'd read the previous review before buying this book as i agree totally. the book is full of mistakes and badly designed puzzles that are impossible to logically complete (and they even admit this in the introduction!). my copy seems to have printing errors on it as well, with parts of the clues being obscured or missing, even though they are nowhere near the edge.
very frustrating to play, there are much better puzzles available online for free... wanted something to carry round offline but the paper isn't great and the binding means that the pages don't fold back easily or stay open flat anyway. very disappointed - would highly recommend people not to buy this book.
