Mom has been collecting these books for years and has read them multiple times. You'll find her initials inside each one with a checkmark. She's 90 years old and still reads with a lighted magnifying glass, but has decided to make room on her shelves.

There are 5 hardcover, one of those is a two-in-one book. The rest are paperback. They are all in good to very good condition. The covers don't all match, but it is the entire 40 book series.
