Libby or: What Happened to the Man with the Dog?

Libby thinks that what happens outside the window of her third grade class is way more interesting than the math class happening inside. One day she sees something upsetting through the window, and from then on the story unfolds. This is a tale of a young girl with a big heart who does not like math. But when in the ‘real’ world, outside school, she searches for the truth and eventually solves the mystery of the man-with-the-dog. This book is the first in a series.
