I think I missed why exactly Tarik began stalking Alexis. Was it simply because she was the nurse that was there when his mother died OR was it because she was his nurse and was there when he became alert? The story moved rather quickly. I liked that once Alexis moved away from the old habit of depending on the 3 exes, she met her future. Tarik was forceful and a bit creepy. The author took us along for the creepy ride as Tarik's obsession grew, which I think was well written.
However, book two added a supernatural element that was unexpected and almost out of place. It changed the tone of the story for me. I think had there been a lead in or hint to it in book 1, it would have come across easier to accept. It took away the tension that the author had expertly built in book one, which was disappointing. Overall, the series was okay, but could have been good had the supernatural element not come into play.
