I echo the praise for this book from the previous reviewers. As mentioned, this is a bit heavy for a beginner, but perfect for someone moving to intermediate stage and attempting to make sense of the grammar (and grammar is all-important in Czech - there's no way of progressing until you've got it nailed). The reservation ? The author's decision to present cases in a non-standard order. It's standard for Czech to list cases in 1-Nominative 2-Genitive 3-Dative 4-Accusative up to 7-Instrumental, but the author has arbitrarily decided to list in 1-4-2-3-6-7-5 order ! If this was the only reference material you ever used it wouldn't matter much, but it's irritating to have to remember that the format differs from all other reference material, so that you find the accusative form where you expect the genitive to be, and so on. But that irritation apart, it's an excellent reference book.
