In the mid-1870s, a violent spray of comets hits Earth, decimating cities, erasing shorelines, and changing the world's climate forever. And just as Earth's temperature dropped, so was civilization frozen in time. Instead of advancing technologically, humanity had to piece itself back together.... In the 21st century, boats still run on steam, messages arrive by telegraph, and the British Empire, with its capital now in Delhi, controls much of the world.

At the end of The Winter, King Arthur fought the battle that forces unity on the warring British kingdoms and now he sets out to face the real enemy - the English (it is one of the great ironies of the Arthur stories that he should have become an English hero when, if he existed at all, he was a great war-leader who opposed the invading Sais). First, though, Merlin leads a perilous expedition into the mysterious west to retrieve a cauldron, one of the treasures of Britain.
