Wrecks of Time

From the Prologue:
"There they lay, outside of space and time, each hanging in its separate limbo, each a planet called Earth. Fifteen globes, fifteen lumps of matter sharing a name. Once they might have looked the same, too, but now they were very different. One was comprised almost solely of desert and ocean with a few forests of gigantic, distorted trees growing in the northern hemisphere; another seemed to be in perpetual twilight, a planet of dark obsidian; yet another was a honeycomb of multicoloured crystal and another had a single continent that was a ring of land around a vast lagoon. The wrecks of Time, abandoned and dying, each with a decreasing number of human inhabitants for the most part unaware of the doom overhanging their worlds. These worlds existed in a kind of subspacial well created in furtherance of a series of drastic experiments…"
Who has the immense power to create entire worlds only to discard them as failures in the backwaters of the space-time continuum?
Who would then maliciously destroy these less-than-perfect worlds and their human inhabitants, and to what end?
Professor Faustus and the loyal men and women dispersed on these alternate Earths have dedicated their lives to eradicating the demolition teams and the Unstable Matter Situations the D-squads create. As they soon discover, much more is at stake, as they fight a seemingly losing battle with the very pattern of the Universe in the balance.
Thought-provoking and full of surprises, The Wrecks of Time weds science, religion, myth, and history into a page-turning narrative, a grand concept tale that has proven to be one of Michael Moorcock's most innovative science fiction works.
