I was always a big Stephen King fan in the 80s and 90s, but haven't been too big on much he's written lately. I suspected that the accident he had in the late 90s (was hit by a van while walking on a road) might have taken a few miles off his literary fastball, thought I did like his conclusion to his Dark Tower series.
Anyway, I just finished "The Cell", which is a couple of years old, and I really liked it. It was like King was back in his "The Stand" form.
The concept: Somebody(thing?) hatches a devestating plot in which every cell phone in existance rings simultaneously, and every person who answers the call basically has their brain erased, and is turned into a murderous zombie.
The book follows a handful of folks who were NOT affected, and their attempt to survive, to figure out exactly what happened... and to find their loved ones...
It's pretty terrific.
