This book is hard to rate. I liked it in the sense that it kept my attention and there were moments when my heart was all in. I didn't like all of the misunderstandings and how many times the author used interruptions to stall the progress of Callum and Harper's relationship. It was like okay, I can buy this once, maybe twice, but after it kept happening over and over again, it got repetitive and I knew what was going to happen as soon as one of them started getting thoughts of telling the other their feelings. The stalker/ serial killer aspect of the story sometimes went a bit overboard. Other than those few things, I found it to be an enjoyable read.
