The Naked God is a science fiction novel by British writer Peter F. Hamilton, the third book in The Night's Dawn Trilogy, following on from The Reality Dysfunction and The Neutronium Alchemist.
They are able to cross back over into this universe and possess the living, gaining tremendous strength, agility and the ability to create and alter matter.
In The Neutronium Alchemist, the Confederation learns of the extent of the danger and imposes a complete shut-down of all interstellar flight to quarantine the possessed on the few planets they have secured a foothold on.
At the conclusion of The Neutronium Alchemist, the personnel of Tranquillity learned that over a thousand years ago a Tyrathca arkship encountered a space-borne entity known as the 'Sleeping God' which exhibited enormous powers which may be of use against the possessed.
When Captain Calvert and the crew of the Lady MacBeth arrived back at Tranquillity, they found the habitat missing, presumed possessed and taken out of the universe.
An infant Kiint, Haile, decides that she cannot let Jay be killed in the attack and activates the Emergency Exodus Facility on her, removing her from Tranquillity as well, to the displeasure of her parents, Nang and Lieria.
The Lady Macbeth journeys to Trafalgar and there reveal the events of their mission to the First Admiral, who is happy that the Alchemist has been destroyed and Alkad Mzu is no longer at large.
A meeting is held and Ione proposes that Tranquillity and the Jovian Consensus join forces to track down the Tyrathca Sleeping God and see what use it could be in the fight with the possessed.
On Ombey, the Liberation Campaign begins with a massive assault on Mortonridge by tens of thousands of regular troops and Edenist bitek soldiers.
Even worse, what energy it does manage to generate attracts the attention of monstrous, immortal, shape-shifting predators known as Orgathé, who attack the habitat with enthusiasm to feed on its power.
There is a gravitational incline in this dimension which leads to a horrifying place called the Mélange, a liquid nitrogen–cold sea of beings trapped in this continuum, unable to accumulate enough energy to escape.
The scientists hope to create a more powerful version that will obliterate all of the tens of billions of souls in the beyond, which becomes a controversial idea among the Confederation government.
Although the first weapon is completed, further research is suspended when a lone Organisation suicide attacker detonates an antimatter bomb right outside the habitat, irradiating it and destroying dozens of ships outside.
He also reveals that they were the actual cause behind the schism between Adamists and Edenists, which began as their attempt to keep bitek technology all for themselves (a plan that was foiled when Wing-Tsit Chong created Edenism).
The operation fails, and Louise finally confronts Quinn at St Paul's Cathedral in London, where he attempts to bring the Night to the Universe by opening a dimensional rift to summon "fallen angels" to Earth.
A confrontation ensues, with Louise, Fletcher, Dariat, Tolton, and a returned-from-the-beyond Powel Manani (the friend of Carter McBride) faced off against the army of the possessed and the entities fleeing the Mélange.
Joshua Calvert uses the god to return every stolen Confederation planet to the Universe, before moving them out of the Galaxy, altering the wormholes to remove the possessed.
