The Turned World has become our own world, almost. The story begins in the 19th century with the eruption of Krakatoa - and the reader is hurled, brilliantly, BETWEEN worlds. Through a series of fabulous landscapes our heroes arrive at the Wall. This is the world of Stone, called Amara - and a world as coherent as McCaffrey's Pern yet as relevant to the reader's own view of the universe as John Crowley's Aegypt series. Edwards is a very significant writer in this respect. The Wall shelters entirely new and strange creatures, such as the Tam, insectile beings that evolve rapidly to sentience whenever there is a breach in the Wall, which they repair and then revert. There are stone-age human settlements in extraordinary buildings, plant life between the cracks in the stones of the wall - and the dragon descendants of characters from the first series. The story is action-packed and the plot extremely strong. Added to this, the central characters develop in totally convincing if startling directions.
