An epic historical adventure set in a pseudo 8th century China, from the author of the 2008 World Fantasy winner, Ysabel. Under Heaven is a novel of heroes, assassins, concubines and emperors set against a majestic and unforgiving landscape.

For two years Shen Tai has mourned his father, living like a hermit beyond the borders of the Kitan Empire, by a mountain lake where terrible battles have long been fought between the Kitai and the neighbouring Tagurans, including one for which his father - a great general - was honoured. But Tai's father never forgot the brutal slaughter involved. The bones of 100,000 soldiers still lie unburied by the lake and their wailing ghosts at night strike terror in the living, leaving the lake and meadow abandoned in its ring of mountains.

To honour and redress his father's sorrow, Tai has journeyed west to the lake and has laboured, alone, to bury the dead of both empires. His supplies are replenished by his own people from the nearest fort, and also - since peace has been bought with the bartering of an imperial princess - by the Tagurans, for his solitary honouring of their dead.

The Tagurans soldiers one day bring an unexpected letter. It is from the bartered Kitan Princess Cheng-wan, and it contains a poisoned chalice: she has gifted Tai with two hundred and fifty Sardian horses, to reward him for his courage. The Sardians are legendary steeds from the far west, famed, highly-prized, long-coveted by the Kitans.
