Unfortunately, I could not warm up to this book. I tried to like it but failed miserably...the book reads like its meant for teenagers and written by a teenager. Sorry. Plot does not hold up, the fact the killer needs to provide lengthy explanation at the end is just childish. Writting style not very engaging. Writting in present tense is unusual, but it just seems to add to the general annoyance here. I could add more but I'm getting annoyed just thinking about it. One just needs to compare some classic writters of this genre.
