This book was... meh. It was predictable. There were no twists, you know who the killer is from the beginning. Because they tell you. Nothing unexpected or surprising happens. Not what I would categorize as a thriller.

I like the book... but there are some definite inaccuracies involved in the descriptions of scuba diving. And that's super nitpicky, and doesn't affect the plot at all, but it's like trying to walk with a tiny bit of sand in your shoe. It just keeps distracting me and rubbing at me the wrong way.

A good book, very well written; but also very slow and incredibly depressing, with a sort of anti-climactic end.

Fast paced, easy read, although I felt it ended a little abruptly. Looking forward to the next in the series.

This book is quite beautifully written; I'm only giving it 3 stars because, while it was well written, it's just not my kind of story or book, and so didn't hold my interest. For people who DO like this genre/story type, it's 100% worth a read.

A 4 star book with a 2.5 star ending.
