Billie and Bobby Boggie are sister and brother Boggies. They love to go on journeys around Bogland, which stretches from West Ditch to East Ditch and from the High Forest to the Low Woods. They never can journey too far, at least not as far as Fogland, home to the Fuming Beings. Also, they must be home in time for dinner, and they hate getting their feet wet. Bogs do get squelchy. Together, they dream of what lies undiscovered and beyond the horizons of Bogland. Billie has a magnifying glass, and Bobby has binoculars, things that come in handy for discovering the flora and fauna of the land. Today, something is awry in the peaceful bog. They have awoken to hear the furious whispers of Ma and Da Boggie. The native peat huts are in peril as turf is mysteriously going missing all over the land. Their Boggie homes are in danger, and a strange darkness has invaded the sunny homeland. Billie and Bobby do what they always do-they go on a journey. This one is different. They are on a mission to solve the turf mystery. Bogland reveals some magical inhabitants who help (and sometimes hinder) them along the way. The charm descends when they reach the Tree where they meet a bearded rhymer. Ragword tells them of the Ancient Deal that protects the homelands between the Boggies and the Fuming Beings. He leads them to a mischievous lion, and they meet a ghost who roams the Bog Woods. They escape the Deep Dark Pond, unravel the mystery of the turf, and together with their enchanted friends and the song of the Ghostgirl, reinstate the Deal with the Fuming Beings. And they get home in time for dinner.
