This is my first book by Ruth Ware. I was not thrilled with the beginning, but once the book … and the cruise … was underway, it improved. There were some serious matters covered, such as a home invasion, depression, anxiety/panic attacks, substance abuse, and sexual assault.
The secondary characters were difficult to keep track of, though that may have been the result of listening to the audiobook. The twist at the end was well presented and pushed my rating from 3 to 4 stars.
