I've only just received the book - I ordered it from Waterstones and it took nearly 4 weeks, so don't expect it in any kind of hurry! There are lots of rather sinister cartoons which make for an entertaining reading - all in all it seems like a good book! It's ALL in Estonian -there is no English or any other language except at the end where there is a useful glossary. The book and CD start right at the very beginning however, with simple greetings and seems quite easy to follow (with the occasional help of Google translate!).
Despite the lack of any English explanations, the exercises are easy to follow in the book and on CD - I look forward to working through it!
