Colloquial Russian: An essential companion while learning Russian on Duolingo!
I found this amazing book online by chance,so here it is: http://www.scribd.com/doc/179876084/05-Colloquial-Russian-The-Complete-Course-for-Beginners-pdf#scribd Hope I helped you!
I love this book. It puts the material in context instead of just giving you endless drills.
By the way, the audio companion is free at the company's website http://www.routledgetextbooks.com/textbooks/colloquial/russian.php
You're right, it presents plenty of information. The older version of the book (it has an ugly orange paperback cover--don't know why it wasn't red, unless it faded) has even more. I bought mine used, and there should be quite a few still available pretty cheap. It's slightly older Russian (1970s) but for what we're doing it is fine.
