Calvin is the one who insists on hearing from this book. Shaemus and Flannery have been there for most installments. Mary and Lucy have dropped in and out, but if they're here, and they know I'm reading, they wander in and they stay until I'm done.
The Stowaways is a great book reminiscent of Mrs. Frisby and the Rats of Nimh.
Ages 7 and up.
