A lifelong dream. A life-threatening quest. A magical ride. Fifteen-year-old Colleen Blackburn finds a door into Tir na nOg, the Celtic land of eternal youth. She and her reluctant sidekick, Jeffrey, must save not only themselves but the faerie inhabitants from a sorcerer who wants to steal the faeries' immortality. Only the humans can save the faeries and find their way home--if they can stay alive long enough.
