By Rachel Bach (=Rachel Aaron author of the Eli Monpress series). There's a sample of it I liked at the end of Ancillary Justice. It seems like a lighter read (I'm done with Ancillary Justice). And I'm a sucker for Ripley-like kick ass female characters. It doesn't come out til tuesday though. Rachel Bach and Ann Leckie will be in a Google hangout with Daniel Abraham on thursday btw.
