Olivia ... an the Missing Toy is the third story that I've read to Sean and Harriet. The series by Ian Falconer continues to delight all of us.

In this story, Olivia is missing her favorite toy. She searches everywhere: under the rug, the sofa, the cat and so forth. She tries interrogating her brothers; it doesn't work.

In the end she finds the toy but finding it brings heart-break. Olivia, though, in her usual way, bounces back and the book ends on a happy note.
