Eoin Colfer's Legend of --

When their mother starts dropping them off at the library several afternoons a week, nine-year-old William and his brother dread boredom and the overbearing librarian, but they are surprised at how things turn out.

Will Woodman has a hard time getting anyone in his family to listen to him, so he turns to his grandfather, who, it turns out, has more terrible sob stories than Will.
