The action scenes are there and the ingredients for a fast paced thriller are in place, but the story and the main plot really don't go anywhere. The narrative seems to be more a social commentary about the danger to human minds because of multitasking and the internet than a real suspense thriller. The revelations about the "big secret" that Grandma Lane has and the resultant case breaking clues that are finally exposed aren't really very exciting and the story sort of limps to a less than compelling or satisfying conclusion. The moral of the story seems to be that humans should stop using computers and have more face-to-face interactions with their loved ones lest we all forget simple things, ruin our long term memories and our brains.
Fine, escapist beach read -- don't expect a high octane thrill ride because it's not found in these pages.
