Lord, Cynthia. Book buddies #1

"Ivy was Anne the librarian's doll when she was a young girl. But now she has moved to Anne's library to be its newest Book Buddy--a toy that can be checked out just like a book. Ivy isn't sure she wants to be borrowed, though. She'd rather go back to just being Anne's favorite toy. Fern, a child who visits the library with her stepfamily, also wishes things could go back to the way they were, when Fern had her dad all to herself. When Fern takes Ivy home, an unexpected outdoor adventure helps both of them find confidence and belonging in their changing worlds."--
