I finished "The Cell," by Stephen King.
There's a saying that a writer sometimes repeats the same story a number of different ways. Back in the 1970s, Stephen King wrote The Stand, a story where most of the world is wiped out by a virus. He re-wrote the story in the late 1980s. This year he wrote The Cell, where an electronic pulse delivered to cell phones causes the majority of the population to go mad or die.
The Cell is structurally similar to The Stand. He's stripped out the science from the book and inserted the fact that those who received the pulse can communicate through their thoughts, but other than that the two books were too similar for my tastes.
