The Reality Dysfunction by Peter F. Hamilton is the first in a sweeping galactic trilogy from the master of space opera, The Night's Dawn trilogy.
In AD 2600 the human race is finally realizing its full potential. Hundreds of colonized planets across the galaxy host a multitude of wildly diverse cultures. Genetic engineering has pushed evolution far beyond nature's boundaries, defeating disease and producing extraordinary spaceborn creatures. Huge fleets of sentient trader starships thrive on the wealth created by the industrialization of entire star systems. And throughout inhabited space the Confederation Navy keeps the peace. A true golden age is within our grasp.
But now something has gone catastrophically wrong. On a primitive colony planet a renegade criminal's chance encounter with an utterly alien entity unleashes the most primal of all our fears. An extinct race which inhabited the galaxy aeons ago called it 'The Reality Dysfunction', and is the nightmare which has prowled beside us since the beginning of history.
The Reality Dysfunction is followed by The Neutronium Alchemist and The Naked God.
