Thanks for the info everyone.
Caregiver - I'm much like you. I loved the first three, and while I finished the fourth, it certainly wasn't my favorite. There were too many loose strings that never came together, and the overall tone was so much more melancholoy. Still, I'm interested, because I think SOMETHING must happen next.
Grace - I almost downloaded Odd is on Our Side to my nook this past weekend, but gladly I read the reviews first. It seems that "graphic novel" is more of a comic book, which is not my style. In addition, it is set back in the day before Stormy passed away, and it seems from the reviews that it really is not much new.
