Salvation Lost (Salvation Sequence #2) by Peter F. Hamilton

Fight together - or die alone....

In the 23rd century, humanity is enjoying a comparative utopia. Yet life on Earth is about to change, forever. Feriton Kane’s investigative team has discovered the worst threat ever to face mankind - and we’ve almost no time to fight back. The supposedly benign Olyix plan to harvest humanity, in order to carry us to their god at the end of the universe. And as their agents conclude schemes down on earth, vast warships converge above to gather this cargo.

Some factions push for humanity to flee, to live in hiding amongst the stars - although only a chosen few would make it out in time. But others refuse to break before the storm. As disaster looms, animosities must be set aside to focus on just one goal: wiping this enemy from the face of creation. Even if it means preparing for a future this generation will never see.
