This "author" is a fraud, this is a fake book and he wrote his own reviews. All 4 reviews rated the "book" 5-stars, but 3 of the reviews were written on the same day that it supposedly published. The number of total pages are also discrepant.
This person has severe psychological problems. He lures underage girls through social media by lying about being a bestselling author and a student at prestigious universities. He then sends them pornography and asks for nudes in return.
