Ahoy there me mateys! So this is a book where the premise sounded fun but I did not love what the author chose to write.  There be spoilers ahead!

The Setting:  Who doesn't love horror on the high seas?  I loved the idea of a creepy cruise ship.  Problem was it felt like the author had never been on one before.  There were lots of descriptions of dining rooms and pools.  Not much that felt like a real ship.  Example: the captain's quarters would likely not be right near the bridge or accessible (ever) to tourists.

The Premise: The idea is that students are going to spend a semester (Seamester) at sea on the cruise ship where then things go wrong.  First of all the book takes place in the first week of the cruise between ports one and two.  Secondly there is no actual idea of what classes or life would be like.  I thought it was going to be a bunch of students who learn about jobs aboard or sea life or the environment or something.  Turns out ALL the students (except the main character) are rich kids whose parents pay for them to be out of the way.  They spend their time drunk, eating, or supposedly joining tourist activities.  Lame and unrealistic.  What is the point of that for a semester?

The Main Character:  While all characters are vapid one-dimensional idiots, the main character is something truly horrible.  Liv has no real personality.  She doesn't use her brain, whines, and dwells in lust.  She spends a ton of time thinking about clothes and how poor she is.  The author tries to go for a "unreliable" narrator.  Problem is the reader quickly knows what is happening and who the bad guys are.  So Liv screams her accusations everywhere, second guesses herself, and believes the adults ridiculous explanations.  Her best friend is one of the missing and she can't focus on that.  The bad guys should have immediately murdered her for being trouble.  I wanted to her shut up and to stop being a moron.

The Solution:  Of course the captain and some parents were in on it.  Of course the social media influencers (the Sirens) are real sirens.  Of course people have to be sacrifices to the sea for the sirens to keep their power.  How Liv and idiot love interest didn't see this was beyond me given how much evidence there was.  Also why did the students need to be the sacrifices?  The sirens switch out a couple of folks during the course of the book with no consequences.  Why not kill crew members?  Or steal people from shore?  It didn't seem to matter who they killed.  Just the number of people killed.  I finished this because I was hoping for an interesting twist or some answers.  Nope.

The Ending: The book literally stops with Liv and dumb love interest stuck in a lifeboat wondering if they will survive.  The end.  No closure.  Is the fire going to swamp the cruise ship?  How is the whole thing going to be explained to the authorities?  Nada.  I thought/hoped that my e-book was missing a chapter.  We don't even get an answer on the weird squid creatures on board.

I ended this book being irked that such a premise ended up with this plot.  I wanted an actual horror book set on a cruise ships - mythical creatures optional.  Stay away from this and read Mira Grant's into the drowning deep instead. Arrrr!
