You're Thinking about Doughnuts — Michael J. Rosen

When Frank's mom has to work late one Friday cleaning the local museum, he finds himself spending a lonely night roaming the dark halls—until a chatty skeleton appears and takes him on an enchanting tour of the exhibits and their surprisingly animated inhabitants. Through objects such as Greek vases and colonial masks of Nigeria, and people like Elvis Presley and Neil Armstrong, Frank emerges from the museum with an enriched understanding of history—and himself.
