Query: My least favorite from Picoult

I have to say, I found the characters in this book somewhat poorly fleshed out, and the plot in general just totally unbelievable. I never seemed to get "lost" in this story...i.e., I always was conscious that these were characters in a book, and not ones I could relate to at that. Then there are some fairly ridiculous tangents that seem to serve no purpose as far as driving the plot forward or illustrating points. It reminded me of a bad soap opera!
