Mercy Not Sacrifice by Dan Parks - Chapter 15
After almost crashing from lack of sleep Johnnie pulls into a truck stop to rest. Jesús goes to sleep in the top bunk and Johnnie goes inside for a shower where all he can think about is San Francisco.
Later, Johnnie wakes up in the middle of the night after hearing his name called and Jesús suggests that he should respond to the one that is calling. In response, Johnnie steps outside for a cigarette full of memories.
