Tanith Lee, winner of the August Derleth Award and several World Fantasy Awards, is best known as a fantasy and horror writer, but she has written several fine SF novels, two of which, Don't Bite the Sun and Drinking Sapphire Wine, form a duology now available in the single volume Biting the Sun.|
The far future has brought freedom not only from material want but also from rules, responsibilities, and risk. You can change bodies and genders like clothes, make love with whomever you want, live forever, and kill yourself as often as you like. You can have everything, except a meaningful life. Then one day a restless soul discovers an act so shocking and terrifying that human society has forgotten its existence.
