A pharmaceutical Faust-a journey through the darker side of ambition. Imagine a drug that makes your brain function with perfect efficiency, tapping into your most fundamental resources of intelligence and drive. Imagine a drug that could make you learn a foreign language in a day and seduce a room-full of strangers in a matter of minutes. Imagine a drug that could make you process information so fast you could see patterns in the stock market. Eddie Spinola is on such a drug. It's called MDT-48. It's Viagra for the brain-a designer drug that's redesigning his life. Eddie's not the only one addicted to MDT, but now that his dealer is dead, he's the only one with a supply. While the drug is helping Eddie make the kind of money he's only dreamed about, he's also beginning to suffer the side effects: Blinding headaches. Violent outbursts. Ominous blackouts. And when Eddie tries to trace the other users, he discovers the terrifying truth. . . The Dark Fields is a feverish reading experience that lingers in your mind long after the final page.
