End of All Songs, The by Michael Moorcock

This book brings to an end the surreal Dancers at the End of Time series and it's an excellent way of ensuring their continued survival. Lord Jagged learns from The Nurse how to create a perpetual time loop to shield the Earth from the destruction of the universe. Jerek and his love from the 19th century are left out of the eventual closing of the loop, preferring to take their chances in the primordial world.

I liked the way this book brought out in the open the consequences of unrestrained use of energy to fulfil fantasies. The Earth is really a dead, dessicated, lump where nothing can grow and survival is impossible without the energy provided by the cities. When Jagged commandeers the cities' energies for setting the loop everything dies, apart from that which the cities did not create. Even the Sun disappears!

I've always liked Moorcock's warped look at things and this book finishes a trilogy as surreal as any he's written.
