There are two versions of science. One is kept secret. When Jackson discovers this, there's no going back.
Bill Mayfield, 19 year old Jackson's grandfather and role model, was gone. When Jackson accidentally stumbles upon what his grandfather left behind it changes everything for him.
Catapulted from England to Hong Kong by a machine that shouldn't exist, Jackson resolves to investigate his grandfather's secret history. He encounters allies and enemies in equal measure as he follows the trail to the United States where the clandestine Fastwalkers are waiting and he must confront the murderous Clean-up Squad.
If data gets ahead of theory, run with the data; if your faith is tested, go with people you trust.
