Creating a series of books at this level is a wonderful help for beginners like myself, who want interesting reading material despite our limited knowledge of Russian. Since I know (and love) the original story, the only difficulty is the new vocabulary. Fortunately, there is a short vocabulary list after every dozen lines or so, which defines the new words. Additionally, the new words are in bold so they are easy to identify. Another nice feature is that all words have stress marks.
I look forward to being able to read the more difficult books in this series, which are adaptions of Russian classics, so that I can become more acquainted with Russian literature while I am improving my language skills.
