The Orphan and the Mouse
by Martha Freeman
Grades 3 & up
(I really wish this book had a better cover. It short sells the exciting story inside by having a really boring cover.)
Caro is a an orphan living in a fairly well-off orphanage in Philadelphia in 1949. A chance encounter with one of the mice who lives in the walls brings an unexpected friendship for both Caro and Mary Mouse. The mice, who forage for food and art (postage stamps) during the night, discover a surprising plot of kidnapping and other illegal schemes and take it upon themselves to warn Caro. There is also intrigue in the mouse world. Helping each other, the mice and the children form an unlikely friendship that helps them both. An exciting story, recommended for grades 3 and up.
