Weird: at the Beginning, I Received a Letter from My Deceased Grandfather.

It wasn't until I was nineteen years old that my grandfather passed away suddenly. All the strange things he experienced when he returned home, as well as the truth behind them, made my skin stand on end. There were only five words written in the letter my grandfather left me: "Run and stay alive!"
