Author Dr. Joel Shulkin discusses his debut novel, Adverse Effects. What would you do if you were the only passenger riding an otherwise empty bus and, when the bus makes a stop, a stranger gets on and sits down in the seat directly behind you? If you are Joel Shulkin, you write a book about it. When Joel found himself in that exact situation, the inspiration for his book, Adverse Effects, was born. Adverse Effects is a medical and psychological thriller with a bit of espionage thrown in for good measure.
