The Tune Is In The Tree is one of these lesser-known eleven novels. Published the same year as Emily of Deep Valley, The Tune Is In The Tree is a children's fantasy story. It tells the story of a little girl named Annie Jo who spends the early months of one summer living with the birds while she waits for her father and mother's return.
The attentive reader will be rewarded by recognizing this story plot as one Betsy Ray decides to write in the final Betsy-Tacy book, Betsy's Wedding: "I think I'll write a story about a little girl going to live with the birds." While it's left to the reader to know if Betsy ever writes the story, Maud Hart Lovelace did in 1930, though it wasn't published for another two decades.
