The mystery of the void at the center of the galaxy, as introduced in The Dreaming Void, makes the perfect center piece around which to tell a complex story. Peter F. Hamilton starts to converge his various story lines from book one as he elevates the stakes across the board. The Living Dream religious movement is convinced that their planned Pilgrimage into the void holds the key to their fulfillment and they are desperate to find the "second dreamer" who will lead them to their promised land. Certain factions within the ANA:Governance continue to supply advanced technology to the Pilgrimage in exchange for coming along, yet their motives for doing so remain unknown. At the same time an alien armada is heading toward human space hell bent on stopping the Pilgrimage at any cost, convinced that if the Pilgrimage reaches the void then the galaxy will be consumed. Times are desperate as the Commonwealth Navy has failed in every attempt to stop the armada and is now considering activating the Deterrence Fleet, which is their mysterious weapon of last resort. And the key to all of this, the second dreamer, remains in hiding wanting nothing to do with Living Dream or their ridiculous Pilgrimage.
