Two batwings up for Bats at the Library, written and illustrated by Brian Lies. It came out this year and has been on lots of best-books lists. The story, written with fun rhythm and rhyme, is super cute: Bats discover that a librarian has left a window open to the public library, and since they love to learn, they fly in to read books all night. The pictures are beautiful, and there’s lots of clever literary references, particularly when the bats get “lost” in the book during storytime.
Brian Lies has several other books out, including another featuring the friendly bats – Bats at the Beach. I will definitely be checking that one out soon!
