"Architects of Memory," the first half of this duo, impressed me with its tale of dystopian corporate government in space involved in a "forever war" with an incomprehensible alien civilization. This novel shifts the focus, as we follow Natalie Chan, true believer in the corporate order, from loyal soldier to vindictive rebel. The opening and close are great, the process of getting there I didn't always find convincing, but I'd still argue that these books are worth your time, and I look forward to what Ms. Osborne comes up with next.
