J. D. Robb hits the nail on the head with this one, with a combination of fast-paced action and baffling developments that reveal facts from Eve's past. The novel grabs the reader's attention right away when we find Reva Ewing in a furious state driving to the house of her best friend. She has recently received information that her husband is cheating on her with Felicity, and her anguish is a combination of the betrayal per se and the fact that the person betraying her is a close friend. Reva is an ex-Secret Service agent who nowadays works with security systems, so she has no problem in accessing Felicity's house, since she was the one in charge of installing the security. But things take a sharp turn for the worse when she finds her husband and her friend dead in Felicity's bed, and Eva is attacked and turned unconscious by the killer, who was still at the scene.
Things are a little different from usual because this time it is Roarke who receives the call. It turns out the Reva works in one of his companies and is also the daughter of Caro, the administrative assistant of the billionaire. In that way, both spouses become involved in the case, Eve as primary investigator and Roarke as a consultant and interested party. It has been a while since we found Eve trying to clean the name of a suspect, the last time was when she had to prove that her friend Mavis was innocent of murder. In this case, her investigation leads her to associate Reva with a project to stop the Doomsday Worm. This in turn leads to interesting developments that end with her finding the truth about her surname and a very disturbing fact related to the abuse she suffered as a child in the hands of her father.
In the last few novels we have seen Eve Dallas and her husband Roarke go through an emotional roller-coaster, and the ride continues in this installment. This is in my opinion one of the most important aspects in this series, since each time we are looking forward to learning more about the characters' past and the new events that occur in their lives. We also observe that other characters show interesting developments in their paths. For example Peabody, Eve's former aide, has passed the detective's exam and is now Eve's partner. Peabody is one of the most charming characters in the series, and her sense of humor works miracles for keeping the narration flowing seamlessly.
The fact that the novel develops in 2059 allows Robb to create a world in which she can apply her view in terms of how society will evolve. For example firearms are banned, there is a vaccine for cancer and droids take care of menial chores. In this novel, almost surreptitiously, the author delivers another tidbit of information about what is going on in 2059, when Reva says: "I carried a weapon when I stood for the President, and once took a hit for her".
I think that writing as J. D. Robb, Nora Roberts has found a niche of readers that were looking for a good sci-fi and mystery mix. I count myself among those readers and will continue to follow this series as long as the quality remains at the high level it has shown throughout its more than fifteen books.
