Delany is one of the most acclaimed writers of speculative fiction. Babel-17, winner of the Nebula Award for best novel of the year, is a fascinating tale of a famous poet bent on deciphering a secret language that is the key to the enemy’s deadly force, a task that requires she travel with a splendidly improbable crew to the site of the next attack. For the first time, Babel-17 is published as the author intended with the short novel Empire Star, the tale of Comet Jo, a simple-minded teen thrust into a complex galaxy when he’s entrusted to carry a vital message to a distant world. Spellbinding and smart, both novels are testimony to Delany’s vast and singular talent.

The Void has existed for untold millions of years. Even the oldest and most technologically advanced of the galaxy’s sentient races, the Raiel, do not know its origin, its makers, or its purpose.But then Inigo, an astrophysicist studying the Void, begins dreaming of human beings who live within it. Inigo’s dreams reveal a world in which thoughts become actions and dreams become reality. Inside the Void, Inigo sees paradise. Thanks to the gaiafield, a neural entanglement wired into most humans, Inigo’s dreams are shared by hundreds of millions–and a religion, the Living Dream, is born, with Inigo as its prophet. But then he vanishes.Suddenly there is a new wave of dreams. Dreams broadcast by an unknown Second Dreamer serve as the inspiration for a massive Pilgrimage into the Void. But there is a chance that by attempting to enter the Void, the pilgrims will trigger a catastrophic expansion, an accelerated devourment phase that will swallow up thousands of worlds. And thus begins a desperate race to find Inigo and the mysterious Second Dreamer. Some seek to prevent the Pilgrimage; others to speed its progress–while within the Void, a supreme entity has turned its gaze, for the first time, outward. . . .From the Hardcover edition.
