Query: compelling, character-driven

I found the first and last sections to be incredibly compelling. The middle was good, though not quite as compelling. I felt like it took me a little while to get into it each time I picked it up, but then read tons in each sitting. However, because it was 650+ pages long, that still meant I had to "re-get into it" several times. It was worth it, though, I'd say. The plot/point was all about the character development, in my opinion, and I thought there could have been some tweaks, and that a little bit of it probably could have been left out (I get the ode to medicine and I liked the suspenseful parts, but I do not need every medical detail just b/c the author is a doctor), but overall, it was well done.
