First in the Underwater Investigation series and a nice solid debut mystery. One hint was dropped a bit awkwardly and made things a bit too easy to figure out a tad early, but other than that, a very good series opener. Solid characters, wonderful setting, lots of interesting dive forensics.
I really enjoyed this series; i learned a lot about BVI & scuba diving, which is always a positive. The author knows what she's talking about and shares that knowledge in an interesting way and with interesting characters.
