The Woman in Cabin 10

The Woman in Cabin 10 was one of those books that once you are into it... you are INTO IT. I remember thinking in the beginning that I had no idea where the story was going then right about at the half way mark I was like Holy $#%# and then couldn't put it down. I remember getting to that part then Ryan came into the room and was ready to go to bed and I was like... I can't sleep right now - this just got real.

Amazon Book Description

In this tightly wound, enthralling story reminiscent of Agatha Christie’s works, Lo Blacklock, a journalist who writes for a travel magazine, has just been given the assignment of a lifetime: a week on a luxury cruise with only a handful of cabins. The sky is clear, the waters calm, and the veneered, select guests jovial as the exclusive cruise ship, the Aurora, begins her voyage in the picturesque North Sea. At first, Lo’s stay is nothing but pleasant: the cabins are plush, the dinner parties are sparkling, and the guests are elegant. But as the week wears on, frigid winds whip the deck, gray skies fall, and Lo witnesses what she can only describe as a dark and terrifying nightmare: a woman being thrown overboard. The problem? All passengers remain accounted for—and so, the ship sails on as if nothing has happened, despite Lo’s desperate attempts to convey that something (or someone) has gone terribly, terribly wrong…

I really recommend this one (it has already circulated through my Aunts) - but make sure to stick with it when you are sort of eh in the beginning. I promise it gets epic!
