It's hard enough dealing with the effects of World War II sending his father and grandfather to the Pacific theater, but now seventeen-year-old Jonathon Thomas has to deal with real and imaginary earthquakes. To make matters worse his school principal has warned him and his schoolmates of potential spies in the neighborhood. How's he supposed to recognize a spy? And why are his neighbors being murdered? And why are people sneaking into his house to search for something? The only comfort Jonathon finds is when he talks with his girlfriend, Jennifer Murphy. What's he going to do when he's banned from leaving his home? Will his recurring nightmare of being swallowed up when an earthquake splits the ground open under his feet turn into reality?
