I finished The Twelfth Card by Jeffery Deaver, which had the unfortunate distinction of being the worst Lincoln Rhyme novel I've read thus far. I'm glad I hadn't stumbled upon it as my first impression of the series or I probably wouldn't have given any of the others a chance. This was hampered by a Mary Sue protagonist, a very unlikely reason for Lincoln Rhyme to have even gotten involved in the killing, and the main characters not even doing all that much detecting during the novel, instead letting the plucky young high school character take care of things on her own. There was some good progress on an ongoing behind-the-scenes plot line at the end of the book but that's about all it had going for it.
But I'm now starting book seven in the series, The Cold Moon, and it's already back to being what a Lincoln Rhyme novel should be about: a serial killer with a fixation on time. I'm especially eager to see how things go because book 8 (which I've already read) had several tie-ins to this novel and I want to see what that's all about.
