Karigan G'ladheon is a Green Rider - a seasoned member of the royal messenger corps whose loyalty and bravery have already been tested many times. And her final, explosive magical confrontation with Mornhavon the Black should have killed her.

But rather than finding death, and peace, Karigan wakes to a darkness deeper than night. The explosion has transported her somewhere - and into a sealed stone sarcophagus - and now she must escape, somehow, before the thinning air runs out and her mysterious tomb becomes her grave.

Where is she? Does a trap, laid by Mornhavon, lie beyond her prison? And if she can escape, will she find the world beyond the same - or has the magic taken her out of reach of her friends, home and King forever...?
