Third in the series of "hilarious enjoyable myth-adventures" from the New York Times–bestselling author of Mythology 101 and Mythology Abroad ( Crescent Blues).   Holl, Keith Doyle's best friend, has finally tied the knot with his beloved, Maura, in the Little Folks' new home, Hollow Tree Farm. Keith has good news of his own: he has started on an internship as a copywriter with a Chicago advertising agency, coming up with slogans and designs for new products, but the project he is really enthusiastic over is chasing air sprites in a hot air balloon.   Unfortunately, one of the agency's client businesses is using the Little Folks' land as a dump for toxic waste. Holl's young cousin Dola sees them do it, but they see her, too. To prevent anyone else from finding out, the men kidnap her and Holl and Maura's new baby, Asrai.   All of the Little Folk are called in to hunt for them. Keith reaches out to the new and wonderful air creatures he's found in hopes of bringing the baby and her brave guardian back to the farm.   Praise for Jody Lynn Nye and the Mythology series   "A great sense of humor." —Piers Anthony, New York Times–bestselling author   "A good, jolly read . . . a book for people who like their fantasy straight up, with fizz, but without cuteness." —Diane Duane, New York Times–bestselling author   "Wonderfully whimsical." —Anne McCaffrey, New York Times–bestselling author
