Gemma is easily one of the most difficult books I have ever read. Even harder because I was actually listening to it on a audiobook. You can't skip paragraphs or lines easily on an audiobook so I had to sit there and listen to every word.I've watched a fair amount of Law & Order SVU and do consider myself not used to but not shocked by most things on this topic. This book gives me a run for my money. I don't think I could recommend it to anyone and I never see myself re-reading it. But it's a good book. Just not one I want to experience again.
