I always snap up the latest Marcia Muller as soon as it becomes available in paperback.
This is the twentieth, roughly, in a series of novels starring Sharon McCone, feisty women private investigator in San Francisco. In this one, her latest assignment takes her to Hawaii, and she is soon drawn into a murder investigation.
This is interwoven as in many of the Sharon McCone novels with the story of her complex relationship with her boyfriend.
I enjoyed reading this, but it is not Marcia Muller's best. Fans of such writers as Sara Paretsky would enjoy these books, but should start with some of the earlier ones.
