For the past four years we have covered the releases of The Chronicles of the Imaginarium Geographica, a series by James A. Owen, in which Tolkien and fellow Inklings C.S. Lewis and Charles Williams are the Caretakers of the Atlas of the Imaginary Lands. October 19 marks the release of Book 5 in the series: The Dragon’s Apprentice.

The Caretakers must fight against their most fearsome enemy ever and attempt to restore Time. They must journey through a forgotten Door from the destroyed Keep of Time in order to seek out the Dragon’s Apprentice. If they fail, it will mean the end of both of the worlds. But success will carry its own price–a price that may be too high even for the Caretakers to bear.

James A. Owen is the author of hit series The Chronicles of the Imaginarium Geographica. He was Guest of Honor at Myth Con 2009. Here, There be Dragons, Book 1 in the series, is being prepared for the big screen by producers Rick Porras and Mark Ordesky, who worked in Peter Jackson’s Lord of the Rings.
