In the high-stakes world of Wall Street, where billions are made and lost with the flick of a wrist, Sheelah Kolhatkar's "Black Edge" delves into the meteoric rise and dramatic fall of one of its most enigmatic figures, Steven Cohen, and his hedge fund, SAC Capital. With the precision of a seasoned journalist and the narrative flair of a novelist, Kolhatkar unveils the labyrinthine story of ambition, greed, and the quest for the elusive 'edge' that defines the cutthroat hedge fund industry.

"Black Edge" is not just the biography of a financial titan; it is a thrilling exposé of the shadowy corners of Wall Street and the loopholes that the ultra-wealthy exploit. Through exhaustive research and unparalleled access, Kolhatkar paints a vivid picture of a system rife with conflicts and corruption, and the government's relentless pursuit to clamp down on one of the most significant insider trading cases in history. This book is a riveting journey through the complexities of finance, the pitfalls of insatiable ambition, and the murky waters of legal and ethical ambiguity that often characterize the quest for the American Dream.
