Just found the synopsis for book 3, due on August 26th.
"Scott Lynch continues to astound and entertain with his thrillingly inventive, wickedly funny, suspense-filled adventures featuring con artist extraordinaire Locke Lamora. Now, in his most captivating novel yet, readers reunite with Locke-and meet the only female Gentleman Bastard… George R.R. Martin has called Lynch "a bright new voice" and his hero, Locke Lamora, "a charming rogue." In THE REPUBLIC OF THIEVES, having pulled off the greatest heist of their career, Locke and his trusted partner in thievery, Jean, have escaped with a tidy fortune. But, poisoned by an enemy from his past, Locke is slowly dying. And no physiker or alchemist can help him. Yet just as the end is near, a mysterious Bondsmagi offers Locke an opportunity that will either save him-or finish him off once and for all. Magi political elections are imminent, and the factions are in need of a pawn. If Locke agrees to play the role, sorcery will be used to purge the venom from his body-though the process will be so excruciating he may well wish for death. Locke is opposed, but two factors cause his will to crumble: Jean's imploring-and the Bondsmagi's mention of a woman from Locke's past: Sabetha. The love of his life. His equal in skill and wit. Locke was smitten with Sabetha from his first glimpse of her as a young fellow-orphan and thief-in-training. But after a tumultuous courtship, Sabetha broke away. Now they will reunite in yet another clash of wills. For the opposition knows of Locke's recruitment and has cleverly secured Sabetha as their countermeasure. Faced with his one and only match in both love and trickery, Locke must choose whether to fight Sabetha-or to woo her. It is a decision on which his life may depend. Lynch's debut novel, The Lies of Locke Lamora (Spectra, July 2006), won the #1 Reader's Choice for Best Novel of 2006 on SFSite.com, and was nominated for the World Fantasy Award and the Compton Crook Award for Best First novel, 2006. And Booklist has written of Red Seas Under Red Skies (Spectra, August 2007): "Fast paced, colorful, funny, with a fiendishly intricate plot... A virtuoso performance, and sf/fantasy fans will gobble it up, though they'll have to fight with caper novel aficionados for every crumb" (starred review). Warner Brothers has optioned Locke Lamora for a major motion picture. Scott Lynch lives in Wisconsin with his wife."
