Cecelia Holland's historical fiction is well known for its immersion in exotic cultures, and Until the Sun Falls , one of her most successful books, takes the listener into the heart of the Mongol horde during the conquest of Russia and eastern Europe in the thirteenth century. Genghis Khan had told his people they were destined to rule the world, and by his death they had made an impressive start. His four sons followed him to the leadership of the enormous new empire and continued the expansion. His eldest son, Batu, launched the conquest of the West—Russia and Europe. In a few years of devastating warfare, the Mongols reached as far as Vienna, mowing down every army that dared face them, like an irresistible force of nature. Until the Sun Falls stars a Mongol general, Psin, whose battles against the enemies of the Kha Khan sometimes seem easier than his struggles with his wives and his son. Wise, brave, and bloody-minded, Psin embodies the passions and dreams of the greatest conquerors the world has ever seen, at the height of their power.
