Book excerpt: It's St. Patrick's Day and Michael McKeever is about to get the surprise of his life. As he heads into the basement on an errand, he hears someone singing--someone who, unbeknownst to the McKeevers, has been living there for years. It's a leprechaun, complete with a pot of gold. Surely this leprechaun can spare some of his treasure to help the McKeevers. But the leprechaun sees things differently. Full-color illustrations.
