Murder Island

"Murder!" she whispered. "Do you think he knows we saw him?" Four separate vacations intersect as four young strangers meet on a ferry to a northern island wilderness. The fun couple they meet over a friendly card games seems more and more mysterious as the week wears on. Days later, as each family looks to head back home, the six of them collide as not one but two horrific events suddenly and permanently alters the course of every one of their lives.
They are afraid, but determined to find the truth...someday. Meanwhile, one of them seeks answers. One of them builds up his body and his courage. One of determines to forget. One of them struggles to remember.
Eventually, all will remember clearly how, in the middle of Lake Superior, a voice admonished them to meet..."10 years from tonight."
