They Dreamed of Dead Ships by Byron M. Kain
It’s the dream that kills you…
Gabe has it good: a steady job, a nice house, a girlfriend he wants to spend his life with, and a well-planned future. (Sometimes he even gets a solid eight hours of sleep.) Until one day, when he finds a weird silver tile embossed with a ship while on a morning jog.
And then the world goes mad.
People are dying by the millions from the silver tiles that spawn in bodies of water. Everyone dreams of a dead ship that is rising from uncharted depths. Gabe and Jennie flee inland, desperately trying to find a way to keep each other safe.
But where do you run when the threat is in your dreams?
