The Experiment [EPUB ebook] 
A suspense thriller

A struggling writer unknowingly becomes the guinea pig in a psychological experiment…orchestrated by his wife.

Each with their own goal in mind, Sarah Hart and her psychologist conduct the study with her husband, Brian, as the test subject. The experiment works and Brian Hart transforms from family man to cold-blooded killer.

But rather than put a halt to the study once results are proven, the psychologist wants more. Tensions mount, threats are made, and all the while, a made murderer is on the loose. 

This thriller will have you hanging onto the edge of your seat for the entire ride. The twists and turns will leave you wanting more, all the way up to the jaw-dropping twist at the end.
