The Devil and the Dark Water

This was pretty confusing and overworked/overplanned I thought. I wasn't sure if there was supposed to be a demon in the story or if he would explain it away.
Spoiler alert- he does explain it away logically, but I spent most of the book imagining he was blaming it on a demon. I don't enjoy fantasy and was thinking that's basically what this was. A pirate ship with a devil after it. The real explanation was a little too complicated for me to care about. I had guessed a bit of it, but not all of it.
Overall this was an ok read but I should have just gone with my gut and not read this. I loved the 7 1/2 Deaths of Evelyn Hardcastle, but this one wasn't as entertaining.
