Little House on the Prairie Books

9 prequels to the Little House books (not complete series). Some are from the Martha Years series, the Charlotte Years and others are from the Caroline Years series. The "Little House on Rocky Ridge" is the first book of Rose's story. Rose is Laura's daughter. Well loved but still lots of life for another reader. Ten books in total. $2.50 each or 10/$20 EDIT: I have discovered that the inside cover of the Rocky Ridge book was written on and the spine is broken, so this title would be no charge. And there's a spot on a couple pages of Little Clearing in the Woods. Reduced price: $2 each or all for $15
