Mythology 101 by Jody Lynn Nye, 264 pages

Keith Doyle, believer in myths, goodhearted nerd, general busybody, and business major at Midwestern University, discovers to his joy—and horror—that a secret village of pointy-eared, magical little elves are occupying a vacant level of the library building. Their leader, The Master, tutors students to pass difficult courses. Marcy, the girl of Keith’s dreams, is already a member of the class. But the library is in danger of being torn down, thanks to a modernization campaign led by Keith himself. The students of the secret class hate him. Marcy is devastated. It looks as though the elves’ home will be destroyed. Keith and the Little Folk need one another. The only thing that can save Keith’s social life is elven magic. And the only thing that can save the elves is the magic of … free enterprise.
