Novel: Genesis by Karin Slaughter

Have got the book. Wanted to communicate with someone else for their 'input'. Only half way through it. Wasn't seeking a spoiler. Will probably fast-forward to the final few pages coz at the moment it is too gruesome and am having difficulty turning the pages, too scared to read even worse happenings.
