David Silver is a homicide cop on a future Earth. He's also a househusband, caring for his home and daughters while his wife Rose is off tending to the semi-clandestine activities of an animal rights group with which she's affiliated. David is currently hunting a serial killer dubbed "Machete Man" because of the brutality with which he kills his victims, When one of the victims escapes, David and his partner Mel, who is also his brother-in-law, are unknowingly set on a path sending them into mortal danger and a clash with a conspiracy currently unknown to anyone. Adding to the mix of characters in the local precinct, some clean, some dirty, Mel and David get a third partner, an Elaki named String. The Elaki are aliens, settling among humans. They are amorphous, highly intelligent, tend to take things literally, have a vestige of a sense of humor, and love tacos. String is a pretty good detective, accepting Mel's barely disguised gibes because he doesn't realize they are insults, but occasionally he does have a salient point to make.
David's hunt for the killer takes him back to the place where he grew up, the worst part of town, the place where it all comes to a head and he learns secrets about the Elaki, the killer, and even his own wife...and his life will be changed forever, especially after he solves the crime.
This is an exciting novel in which the sci-fi aspects of the story meshes well with the police procedurals but don't overwhelm them. David's inner conflicts about the danger his wife places herself in, his slight jealousy over her partner, the animal-loving Haas, his love for his daughters as well as his occasional exchanges with his brother-in-law make him into a very three-dimensional character. String and the other Elaki encounters are also given personalities which are, if not likable, at least interesting. When he is nearly killed and insists on continuing his investigations in spite of blatant warnings to back off, the bravery he fears he's lacking shines through. Though there are no overt clashes, the enmities between aliens and Earthlings, while not necessarily at the hatred level , are at least prejudicial, as evidenced by Mel's continual jabs at String, added more tension to the mix. Needless to say, occasionally Stringy gives as good as he gets and by the closing of the case, Mel's attitude toward him has changed.
It's an easy read but not a simplistic one...and definitely an enjoyable narrative.
In the villain, Ms Hightower has created one of the most frightening and evil men ever encountered in fiction. He's oily, devious, cruel, and enjoys the fear and pain he instills in and perpetrates upon his victims. This is a character who revels in disaster and truly deserves whatever happens to him. One might wish he could be brought back for future entries in this series to again bedevil Detective Silver who has a right to a vendetta against him.
As I read this novel, I found myself hoping it was the first in a series. By the time I finished, I was glad to learn it was. I will be looking forward to reading the rest.
