Congratulations to Kelly Hale, who's been signed up to write the fifth Faction Paradox novel, Erasing Sherlock.
Kelly's an excellent writer, visceral and funny by turns. She's one of the ten minds jointly responsible for The Book of the War, and co-wrote Grimm Reality with Simon Bucher-Jones (another author who I very much want to see a Faction novel from). She also produced one of the best stories in Walking in Eternity.
Erasing Sherlock is apparently a Holmes pastiche, which sounds like an excellent addition to the range (and ties in oddly well with Of the City of the Saved...). By all accounts it's shaping up to be a fine book, as it should be with such an author to its name. I'm really looking forward to it.
