Half-resurrection blues

I got this book through generous donation to Worldbuilders Fundraiser. It is a simple romp and I found characters frustrating. Murdering a guy, deciding he loved his sister(!) based on a photo. (Who cares about anything else?) And of course she falls into bed. With brother's murderer. Who only wants to get as far as he can before she finds out. Wanted to like it after winning it.

Half dead, half alive Carlos Delacruz works for the New York chapter of the Council of the Dead. It's the Men in Black for spirits, ghosts and demons. When he stumbles on a plot to break the barriers between the living and the dead fuelled by other “halfies” like him straddling the line between the living and the dead, he will need all the resources at his disposal including a house spirit, ghost partners, voodoo doctor, surgeon and a kid working the cash at a corner store. New York noir with a spiritual bent and lots of diversity. There's enough hints to a larger, complex world that the book has already been optioned for a possible TV series.
