Sword and pen - Rachel Caine

Jess Brightwell and his friends have achieved the impossible: masterminded an uprising against the Great Library, and toppled its corrupt regime. But while the battle is won, the war is far from over. A new Archivist must be crowned, one capable of weathering the political storm. With the Library reeling from the coup, foreign nations are circling, eager to plunder the world's knowledge. And the old Archivist, their despotic enemy, has fled into hiding and plots from the shadows. Threats could come from anywhere, at any time. Any of Jess's friends could be wounded or killed in an instant, and the future of the Library itself hangs in the balance.
