Stranded: A Minecraft Adventure

You drop a minecraft character in the middle of the desert. Their only item is a book written by you that has the coordinates to a fake safe house in the desert. At the fake safe house, you leave a second book in a chest that gives the character another set of coordinates that leads them to a sign with the real safe house coordinates on it. The middle of the desert is the origin point (0,0). The fake safe houses are the blue squares and the real safe houses are the red squares.
