Formulaic, easy reading detective/serial killer story featuring a female cop with a fatal disease as the main protagonist. The kind of light, no-brain book that's good for long airplane trips or the beach, and that's probably the highest praise I can come up with. I did like that the main characters are women, even though their characterization is fairly shallow and stereotyped. Still, good effort, good to see more authors trying to include more women in interesting roles.
