From award-winning author Tim Lebbon comes this harrowing tale of an epic journey, crossing the forbidden boundary separating us from all we fear the most.…

To the unknown corners of Noreela, the Voyagers have traveled, returning with fantastic tales of their journeys and discoveries. But no one has ever returned from the Great Divide: a sheer cliff soaring miles above the clouds and rumored to be the end of the world. Until now.

Voyagers Nomi Hyden and Ramus Rheel would be mortal enemies if their lives and fates weren’t so closely entwined. But now the unlikely pair are brought together for what will be their greatest—and perhaps final—journey. When a grim wanderer named Ten arrives with an ancient parchment he claims to have brought back from the Divide, its arcane glyphs hint at the existence of a realm most consider a myth...and at something amazing sleeping there.

Accompanied by the warrior Beko and his band of armed Serians, Nomi and Ramus set out to discover the truth behind the legends. But soon ambition drives them apart, this epic Voyage becomes a race...and each Voyager is faced with a choice that may alter the history of Noreela forever.
