Ophelia and the Marvelous Boy, Karen Foxlee. Ophelia Jane Worthington-Whittard, a young cynic of anything beyond the ordinary, moves to a museum with her sister, Alice, and their father who takes the job as curator of swords. Upon exploring the seven floors of the museum which houses everything from stuffed elephants to crowns and tiaras, she comes across a boy trapped behind a door on the third floor. After accepting that he is real and needs her help to free him from the Snow Queen, she sets off on several adventures to obtain three keys necessary to open the door. She must endure talking ghosts, hungry birds and the watchful eye of Miss Kaminski. Throughout the story, she learns the story of how "the boy" came to lose his name and how he got trapped for hundreds of years behind the door.

This would make a great read aloud. I found it to be fun with just the right amount of intrigue to keep kids wanting more. Once the kids know the book, it would make a marvelous mentor text for how to use lists; they are prolific throughout.
