Have you read the Betsy-Tacy books? They were written by Maud Hart Lovelace. They were first published in the 1940's. I have to admit these books have a special place in my heart. I was an avid reader as a child and I read every one of these books several times. I feel like I grew up with Betsy, Tacy and Tib. The books follow the girls from a young age all the way through Betsy's wedding. I especially love the books from the high school period.
These historical fiction books are written beautifully. They transport you to a simpler time in life. The setting may be long ago but it is easy to connect to the characters and the problems they have.
They have been republished with new covers and pictures. Personally, I prefer the old ones. Great literature that will transport you to another time in America.
