Living on a boat your entire life has some positives. Like the fact that swimming is apart of your daily schedule and the air isn't polluted. Negatives include but are not limited to: being stuck with your sibling 24/7, never getting to escape your parent's demands or your personal hater(s) at the school. Seriously, a school, mall, and market... on a boat. Things really couldn't be weirder, but for the boat locked people, a double murder means they could be next. And two teens are the prime suspects.
