BZ Gundhalinu left Tiamat before the Stargate closed, cutting himself off forever from the woman he loves: Moon Dawntreader Summer is now the Summer Queen and BZ knows he can never again be her lover.

An outcast, he travels to the planet Four: a wild planet where all the rogues and ruffians of the universe gather to plunder the mineral wealth of the vast, unchartered wilderness known as World's End. But there is more to World's End than dangerously-won riches. There is a chance for BZ to unlock the secrets of Old Empire technology - and to rediscover his soul, his destiny and his love.
