The Rosetta Mind comes out Aug. 25. I have not read it, so I can't review it, but this is the second from Claire McCague in this series. I loved the first -
The Rosetta Man - so very much. It is a first-contact story that takes the problem of alien communication so seriously it becomes pretty funny. No babble fish or universal translators here. The Rosetta books posit aliens that are, well, alien. Not the inscrutable kind, the more squirrely variety.
