Blue Genes by Val McDermid

Kate Brannigan, Manchester's tough-talking crime-stalking PI, isn't just having a bad day. She's having a bad week. The worst week of her life, in fact. Her boyfriend's obituary is in the newspaper, her plans to capture a team of heartless crooks are in disarray, and a Celtic neo-punk band under siege wants her to rescue them from the saboteurs who are trashing their posters and gigs.

Kate can't even cry on her best friend's shoulder because ace crime reporter Alexis has a few worries of her own. Her girlfriend Chris is pregnant, and when someone involved in pioneering illegal fertility treatment is murdered, Alexis needs Kate as she's never needed her before.

Delving into the alien world of medical experimentation and the underbelly of the rock music business, Kate confronts betrayal and cold-blooded greed as she fights to save not only her livelihood but her life.
