This is book 4 in the Little House on the Prairie Series
Some things that are of interest in this next book:
1. Mary is blind due to scarlet fever, and there is a new sister, Grace. I don’t think of this as a spoiler because it tells you this on page 1 or 2.
2. Railroads and Trains
Overall I think this was an interesting and fun read. It is a great continuation of the LHOP series.
