Family Honor is a Sunny Randall novel. Sunny is not just another Parker detective. She has her own series, but she's also rubbed elbows with characters from Parker's other New England based novels, the Spencer and Jesse Stone series to be specific. Family Honor is the first in the Sunny series. I've decided to start at the beginning and reread the ones I missed.
Family Honor is about rescuing a runaway and cleaning up the mess that triggered the run. Sunny's personal life and her dog are tangled up in the story, as is her extended family, the cop side and the mob side. It's a very interesting mess. Highly recommended.
