This is book number 1 in the Betsy-Tacy series.
Best Friends Forever
There are lots of children on Hill Street, but no little girls Betsy's age. So when a new family moves into the house across the street, Betsy hopes they will have a little girl she can play with. Sure enough, they do—a little girl named Tacy. And from the moment they meet at Betsy's fifth birthday party, Betsy and Tacy becoms such good friends that everyone starts to think of them as one person—Betsy-Tacy.
Betsy and Tacy have lots of fun together. They make a playhouse from a piano box, have a sand store, and dress up and go calling. And one day, they come home to a wonderful surprise—a new friend named Tib.
Ever since their first publication in the 1940's, the Betsy-Tacy stories have been loved by each generation of young readers.
Maud Hart Lovelace (1892-1980) based her Betsy-Tacy series on her own childhood. Her series still boasts legions of fans, many of whom are members of the Betsy-Tacy Society, a national organization based in Mankato, Minnesota.
