Mucumber McGee and the Lunch Lady's Liver

In a dismal old schoolhouse down by the sea,
there was a young boy named Mucumber McGee.

Lunch had begun, and was nearly complete.
Would there be any food for Mucumber to eat?
Alas, not a hot dog, not even beef stew,
only a plate full of brown, lumpy goo ...
Originally published by HarperCollins in 2008, The Lunch Lady's Liver is the second book in the Mucumber McGee series.
