Louis the Trumpeter Swan is born without a voice.  So, with the help of his good friend Sam, he learns to read and write instead!  But this doesn't solve the problem of how to woo the lovely Serena.

Stuart Little is no ordinary mouse.  Though he's shy and thoughtful, he has a very adventurous spirit.  When his best friend, a little bird called Margalo, disappears from her nest, Stuart goes out into the wide world on his greatest adventure of all to look for her.  But will he find her?
