Okay...this one's going to be a little hard for me. The truth is, I liked this book, but I didn't love it. In fact, I had several issues with it.
What I liked
I liked the pacing. I liked the introduction of little details in the beginning which turned out to be significant later. I'm also a sucker for a good mystery, so I felt compelled to keep reading and find out what, exactly, really did happen to Marissa Taylor. Overall I found it to be an enjoyable read which kept my interest from beginning to end.
The Problems I Had
1st: There are quite a few typos. This is something I'm normally willing to look past because, lord knows, I understand how easy it is to miss those things, especially when you've proofread your book so many times it doesn't even look like words anymore. But this book has a heck of a lot of them. It just needs a couple more read-throughs with the editing glasses on before it's really ready for public consumption.
2nd: There is a recurring grammatical error. I'm always careful to differentiate between typos and errors. To me a typo signifies that the author knows better, but just missed something. An error is an indication that the author does not know what is correct. I only found one major error, but still it bugged me. The author repeatedly used "drug" for the past tense of "drag" instead of the correct "dragged." A small detail, but one that stuck with me nonetheless.
3rd: The book takes place in North Carolina on the Outer Banks. This is, of course, on the East coast, but there are two moments in the book where the narrator describes watching the sunset over the ocean. The sun does not set over the ocean on the East coast. Since it is the Outer Banks, it's possible that the character was actually watching the sunset over Pamlico Sound, but if so that should have been specified.
4th: I questioned the believability of the ending. I won't give out any spoilers, but it just made me scratch my head and wonder, "Is that what would really happen?" I wish it had gone into more detail about the investigation and the trail so I would maybe see some of the evidence and courtroom arguments that would have led to the end result.
Nonetheless, I'm glad I read this book and would definitely recommend it to others. I just felt I needed to point out the above so people will know exactly what they're getting with this book.
