Found my notes on Shooting at Midnight, they are more articulate (I think) than what I wrote the other day:
Feel very ambivalent about this book. Not because of the heroine per se: she’s a strong, asskicking main character, independent, flawed. But on a personal level, her fatal flaw is one that I struggle to find sympathy for (she’s a junkie). It’s hard to make even an ex-junkie sympathetic to me, because addiction is hard to overcome, even on a daily basis. And her character is set up to fail from the start, based simply on who she is: she has isolated herself intentionally, without a support network. And her choices and judgment weren’t trustworthy; even before she was back on drugs, she was flaky and undependable, and I never believed the reason she sacrificed everything was abiding friendship, more like an excuse. Also, ultimately, she’s a criminal and a cheat, and her willingness to get her killer friend off was just another example of extreme loyalty grown in a drug culture.
