This book does (intentionally) take a long time to get through, crammed as it is with invaluable information. I can see where A. Allen is coming from, it probably isn't the ideal book for the tourist who wants to learn quickly how to say hello and order a coffee. If that's what you're after, try the colloquial or teach yourself series. If you want a thorough grounding in the grammar and vocabulary, to the point that you can construct meaningful sentences of your own; set aside a few months, prepare yourself for some hard work and buy this book - it's the best there is!
