Brainrush by Richard Bard
Before he slid into the MRI machine, Jake Bronson was just an ordinary guy with terminal cancer. But when an earthquake hits during the procedure, Jake staggers from the wreckage a profoundly changed man, now endowed with uncanny mental abilities.
An ocean away, Luciano Battista wants a piece of Jake’s talent. Posing as a pioneering scientist, the terrorist leader has been conducting cerebral-implant experiments in a sinister quest to create a breed of super jihadist agents…and Jake’s altered brain may be the key to his success. But Jake refuses to play the pawn in an unholy war—and when an innocent woman and autistic child are taken hostage to force his cooperation, he embarks on a jihad of his own. Jake and his band of loyal 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.
