I've said this before, but I'll say it again, I like Judge Deborah Knott. Yes, she gets involved in solving murders; however, she's much smarter about it than most cozy heroines. Also, as judge, she's involved at least tangentially on a professional level.
In this one, she's really involved on a personal level - she knew the victims. As the countdown winds down to her wedding with childhood friend and "brother", Dwight, she's finding her way in how involved she can be in Dwight's cases and still remain impartial as a judge. It's tough for Dwight too. Obviously, as his love and partner in life, he would like to discuss and confide in Deborah, but doing so, on both their parts can compromise their professional careers.
I find these books well above most cozies written today. You have an intelligent, professional woman, who does not act impulsively and stupidly. Yes, she does find herself involved in very dangerous and life threatening situations, but she didn't get there by going off half-cocked and confronting murderers because she can't contain herself and has no impulse control. Hear that cozies.
