"The Legend of Spud Murphy," Eoin Colfer, Puffin Books; March 2004; 90 pp.

If you have no clue why your older siblings rave about author Eoin Colfer, you're probably too young to have read about the wild escapades of Colfer's hero, Artemis Fowl. But his latest book, "The Legend of Spud Murphy," is your chance to find out why his fiction is worth all the fuss.

Marty and Will have been sentenced by their parents to spend their holidays where no other boys their age would dare to go: the local library. Being surrounded by shelves of books that look like they're about to jump off the shelves and bore you to death is bad enough. However, there's one thing -- or one person -- that's even worse: Spud Murphy.

Spud, otherwise known to unsuspecting grownups as Mrs. Murphy, is the local librarian. But Will and Marty, like all young unfortunate boys who've done time with Spud, know that their mother's assessment of her as a "lovely old lady" is way off the mark.
