I read this book many years ago when I was in Year 3. Reading it again as an adult, I can see why I found it so interesting and enjoyable. I was at that age when your horizons begin to widen, and you realise that not everyone lives are the same as yours. So to read a story set in Russia and Siberia, with their long, cold winters blanketed in snow and long summer days was fascinating to a child living in a rural Australian town who had never even seen snow. But as a child living in a Christian family, it was also incredible to me that there were people in the world who couldn't easily get a Bible when everyone in my household had their own, or that someone could be sent to prison simply for being a Christian. So all in all, this book was an eye-opener for me and even now that it is a bit dated, it is still worthy of being read by young children. It may not be a piece of high-quality literature, but it is well written and can be easily understood by its target audience.
