Query: Needed to be about 1/3rd shorter

I really wanted to like this, but I couldn't finish it. About 4/5ths of the way through, after the last tedious plot twist I finally decided this wasn't fun any more, and not even worth reading to find out the ending. Her writing really needed tightening. She overindulged in extensive passages with lots of technical jargon, labored needlessly over character development, and after the nth foray onto the dream Titanic, where she seemed to go about a foot further every time, it was just too much for me. Often she seemed like she was writing for neurologists who were Titanic buffs, which is an awfully small target audience. I am actually fascinated by neuroscience and psychology, and it was starting to bore me. Those of you who aren't all that into it, I can't imagine would like it better. I also did not feel the obvious jabs at the Titanic film, although I too didn't like it, were really necessary, and they kind of knocked me out of the book's world each time.
