My first Darcy Coates was a success! I've been meaning to start reading her books because they're always recommended as good horror or mystery. This was both, but the horror was lighter than I expected. It's more dreadful than horrific, and unsettling, but it was effective to me. 

I do think this was a little too long. I think it could've been, like, 150 pages less. The beginning was great and it dulled a little in the middle, but overall, it's a solid horror mystery that did give me the creeps. Being underwater and exploring a mysterious sunken ship is scary on its own, so adding paranormal elements just makes sense and it was well done, in my opinion. 

It was atmospheric and tense even though it gets super slow in the middle, I enjoyed the dual timeline, and the characters were good. I expected more from the ending, but it didn't ruin my experience. So this is verging between 3.5 and 4 stars for me!
