Stranded and Hurt

Twenty-one year old Kinsley Balthasar was always the happy do-gooder that everyone loved. She was rarely ever caught upset, let alone sad or mad. People saw her as witty and cute with her quick and sarcastic comebacks. Though she never understood much of why any guy paid attention to her, she never questioned it. Growing up with her Grandfather always around, she was given many life lessons. He is the reason she is always so upbeat.
Kinsley Balthasar, more commonly known as Kinsy or Kins, always remembered the oddest thing that her Grandfather had told her, in the short time she had to know him, and those are the things that she valued most. Every tip he gave she has written down and set in a jar.
A year ago Kinsley remembered that her Grandfather had always told her to keep her belongings safe from the water, so she did just that. She invested in a water proof backpack and when she went on her cruise, it went everywhere with her with multiple items in it; a pen, an empty notebook, a pocket knife (concealed as a hair brush, of course), and a spare set of shorts and a t-shirt (as well as a hoodie because it would get cold at night over the ocean), and that was really it. She didn't carry her phone with her on the cruise. She left that in her luggage.
The cruise was for her engagement. Her fiancé took her on it, a cruise being the one thing she has always wanted, and it was perfect. Key word?

It WAS.
