Prior to the MRI, Jake was dying of a brain tumor. Post MRI, he has acquired extraordinary powers, as his mind's inherent capabilities have been awakened. He then does extraordinary things.
The book thus far is fun. It isn't very deep, but the plot is interesting enough, the character seems decent, and all is well. Sure, things stretch credibility a bit during a fund raising scheme at a Monaco casino, and with the ability of the hero's buddy to acquire a full team of highly trained and well equipped mercenaries essentially overnight. But in this kind of fiction, the need to suspend disbelief for plot advancement is practically de rigueur.
Things get a bit dicier when aliens enter the picture.
In spite of that, I do plan to read the next volume in the series. Maybe through Amazon's Lending Library
