I just finished reading this book, and it was great! It definitely helped with the acquisition of new vocabulary and understanding much better some Russian motion verbs and the use of prefixes in verbs as well. The format is friendly, and the audios are of outstanding quality. I could understand (without reading first, I always listen to the audio before reading for the first time) more than 70-80% of what was said in the slow audios at the first listening, and of course even more after reading the chapters! I sincerely hope we can get more readers of many degrees of difficulty in the future. I will buy them without hesitating!
