Old Town in the Green Groves

I am really glad I started the Little House books again.  I'm really excited for the show on Friday, so I grabbed 2 more in the series.  Old Town in the Green Groves is by Cynthia Rylant and is about Laura's lost years.  She never really wrote about this time in her life except for a couple journal entries.  I'm interested in this one because Rylant said this is when the Ingalls family moved to Iowa.
