Ruth Ware is a great mystery/thriller writer. She went from a secluded cabin in the first book of hers that I read to the open water of a boutique cruise ship. The Woman in Cabin 10 keeps you on the edge of your seat from the first page.  Lo is the main character and has a personally terrifying experience before leaving on a work trip to review the newest European boutique cruise ship. But her terrifying experiences continue on board. I won’t give anything away, but I highly recommend this book as well as Ruth Ware as an author.
