This is a sequel to The Verifiers. I like its blend of mystery and science fiction with a dash of (mostly unfulfilled) romance, along with a side of sociopolitical commentary. The setting is either present day or very near future, so the science fiction aspect is speculation about what could be going on beneath the surface of the world we see. Nearly all of the important characters are women, and it's just presented as a given that they are whole people independent of any men.
