Limitless

Imagine a drug that made your brain function to its full potential. A drug that allowed you pick up a foreign language in a single day. A drug that helped you process information so fast you could see patterns in the stock market. Just as his life is fading into mediocrity, Eddie Spinola comes across such a pill: MDT-48 - a sort of Viagra for the brain. But while its benefits materialise quickly, so do certain unwelcome side-effects.

A burnout at thirty-five, months behind on his book, low on cash, and something of a loser, Eddie Spinola could use a shot in the arm. One day he randomly runs into Vernon, his ex-wife's brother, and his ex-dealer. Now employed by a shadowy pharmaceutical company, Vernon has something that might help: a new designer drug that stimulates brain function. One pill and Eddie is hooked. His book is finished within days; he learns and synthesizes information at a frightening rate; and he can go a long time without sleep or food.
