Just think about the book you are reading now, or one you've read before, and tell me something you think goes with it and why.
The something can be another book, a movie, a song, a ballet, a drink, a special food or meal...no need to get Proustian about it, but if madelines are involved, it's okay.
* the protagonists are a brother and sister
* the story takes place in an ultra-cool setting: a time-traveling/time-stopping library and the Metropolitan Museum of Art
* both books speak to the sense of adventure and the ability to do something big/important/wonderful without the help of (or little help from) adults.
Both of these books make great chapter books and/or read-alouds for both girls and boys! I hope you'll check them out!
