"You may wonder why I tell you this, but bear with me. I didn't realize it then, but I had stumbled on something of enormous importance. Something that will redefine mankind. Something that could redefine you."
Adrian - posthuman 

A mass-market drug promised to boost intelligence. The world embraced it and soon everyone was a genius - but only for a while. The long-term effects crippled world societies, but a select few experienced much greater changes, becoming more than human. 

Tom Devine is hired to capture one of the posthumans by the company that introduced the drug in the first place, and finds himself part of a new world rising from the ashes of the old. 

The God Drug is a thriller set in the very recognisable near future.
