Book Review-Dark Inside

I am really torn with this book. I tend to either love or hate a book, but with Dark Inside there were things I loved and there were things I hated. The Author left me scratching my head a bit because we as readers were given absolutely no answers as to what is going on. I understand that this is probably the first book of a series, but I felt we could have been given a little something, but we were given nothing at all. 
Dark Inside follows Aries, Clementine, Michael and Mason who are trying to survive in a world gone mad. It starts as any normal day would, but then there are devastating earthquakes all over the world and something is unleashed turning humans into killers. For these 4 teenagers they must learn how to survive and who they can trust. 
The premise’s for this story is really what dragged me in and in some aspects it didn’t disappoint. I really enjoyed the idea of the whole humans turning into killers and the end of the world as we know it concept. Like I said in the beginning of this review my main issue is we weren’t even given a breadcrumb of a hint as to what is going on. Another thing that bothered me with this story is it’s told from four POV’s. To me any more than two POV’s gets to be a bit much. It takes away from the story all the bouncing back and forth. Also I found myself backtracking a lot trying to figure out which character I was reading. I felt they really weren’t given their own personalities. When reading they all sounded the same. I also didn’t really like the POV that popped up off and on during the story called Nothing. I mean hopefully later in the series it is explained to us, but for me in this story it did absolutely nothing for me. 
Ok onto what I loved the nonstop action in this story really is what kept me entertained. Jeyn Roberts knows how to write good action scenes. I also liked how the 2 main female characters weren’t wimpy weaklings who needed a man to take care of them. They took care of themselves and in a few scenes kicked some butt. There really isn’t much in the way of romance in the story. There are little hints of romance but none of the instant oh I love him I can’t live without him that tends to be in young adult books today. 
Overall I liked this book but I wasn’t crazy about it. I will definitely read the next one just so hopefully I can get some answers.
