Right! The review of the April 2007 Analog is already up on the Tangent Online page!
Although I haven't even seen the March 2007 issue yet, reviewer Steven H Silver has fired up his time machine to check out the anti-antepenultimate (points to anyone who understands what I mean by that, but no, Analog is not folding) issue of Analog, which includes "Things That Aren't," co-written by myself and Bob Greenberger. (Bob uses the pen name "Robert Greenberger," though.) Of our story, he says:
The story’s tension comes down to how Trevor [the villain] will be caught, and the authors handle that detail quite well. In the process, they showcase the divisions that can occur within a team, as well as the method used for testing hypotheses and controlling their dissemination. Valiquette [the FBI investigator]...could easily become the focus of a series of science fiction mysteries in which scientific theory is the basis for the crimes he is investigating.
I hope he will be pleased to hear that a sequel is in the works.
