As a beginning student in Mandarin Chinese, I've been wading through a galaxy of books--phrase books, grammar books, writing books, and text books. The best I've found so far is Chinese 24/7, which I review in today's Tribune. This book has really helped me out a lot.
Here are some related links, as promised in my review:
The book's author, Albert Wolfe, is also author of Laowaichinese.net, and it's via this site that I discovered Chinese 24/7.
Chinese 24/7 has associated audio files that are free to download at Chinese247book.com, which also carries more information about the book.
