I've showcased some of my favorite books below as well as several good ones on Unicorns.
Note: One of favorite books Judy Journey's by Lois Lenski is out of print, but if you are interested, I'm sure that Amazon could hunt it up for you. They have already found 2 out of print books for me. The Boxcar Children and the rest of the books in the series were read to me several times in school. The story is timeless and teaches a good on family and self-reliance.
