From Paizo's website:
A strange light in the sky holds a danger unknown for ten thousand years! Deep beneath Golarion's surface, the greatest shame of the elves is stirring once more. Seething with hatred, the drow have come up with a plan to wipe out their ancient enemies and bring a second Age of Darkness. And this time, there's only the heroes to stop them...
In the Second Darkness Adventure Path, the heroes venture from the Varisian pirate haven of Riddleport to an island overrun by extraterrestrial terrors, a fallen forest capital of the elves, the subterranean realm of the drow (where they are disguised as drow themselves), intrigue-laden elven courts, and a mysterious realm forgotten by time itself, known as the Land of Black Blood.
