This book is filled with lots of suspense, mystery, thrills and horror. I like how it kind of starts with a look into the killer kidnapping a new victim and then how it goes into the story showing how they are trying to find this victim before it's too late. I also like how the new crimes seem to connect to the old. I also like how they told of one of the old crimes being solved. Also what they name the killer is very interesting and they tell you why he's named that while you're reading. I also learned some new facts. One about butterflies and I loved that. It really keeps you on the edge of your seat and wanting more!! Cannot wait to see what other stories this author comes up with!!
