From the first page, Dark Waters takes off running and doesn't stop. I enjoyed the ride. It's apparently a sequel to Dangerous Waters, but I didn't really feel like I was missing anything in reading this. I just want to go back and read Finn and Holly's story now. I loved Anna and Brent. Because Brent got to know Anna through her letter, I didn't feel like their romance was rushed. While there wasn't a lot of suspense, there were a couple of surprises in the end. I definitely recommend the book.
