When the Babies Came to Stay by Christine McDonnell; illustrated by Jeanette Bradley. 2020. Digitally illustrated using Procreate for iPad. Published by Penguin Random House.
Brief summary: Four babies with notes asking for someone to take care of them mysteriously appear on an island The librarian decides to take them after everyone gave reasons that they could not. She shortens the names of the babies to A, B, C, and D and gives them her last name, Book. Several of the islanders help raise the babies.
When the babies become older and attended school, they began to have many questions about where they came from in which the librarian did not have a definite answer and emphasized that they should focus more on where they were going.
Comments: I thought it was funny that the librarian lived above the library. I often felt that would be a perfect place for any librarian and children to live.
