Brainrush by Richard Bard

The Wall Street Journal #1 bestseller that Publishers Weekly called “a terrifically entertaining thriller!”
When terminally-ill combat pilot Jake Bronson emerges from an MRI with extraordinary cognitive powers, everyone wants a piece of his talent–including Battista, one of the world’s most dangerous terrorists. To save his love and her autistic child, Jake and his friends are thrust into a deadly chase that leads from the canals of Venice through Monte Carlo and finally to an ancient cavern in the Hindu Kush Mountains of Afghanistan–where Jake discovers that his newfound talents carry a hidden price that threatens the entire human race.
