I have used this book with my Polish teacher when I was having lessons. It is a good book but I would think for a beginner using it alone without the guidance of a teacher, it would be too difficult. Someone gave me a copy of it, but I have seen it ob sale in Empik megastore in Warsaw and also online.
I bought my copy through Grant and Cutler, a London-based foreign language bookshop.
It is written by the guy who runs the "Polish for language for foreigners" course at the Jagiellonian University in Krakow.
I found the book to be a useful book to work through on my own (It's in English). If I am with a teacher I use Hurra po polsku, which is written in Polish.
