Susan Fowler was just twenty-five years old when her blog post describing the sexual harassment and retaliation she'd experienced at Uber riveted the nation. Her post would eventually lead to the ousting of Uber's powerful CEO, but its ripples extended far beyond that, as her courageous choice to attach her name to the post inspired other women to speak publicly about their experiences. In the year that followed, an unprecedented number of women came forward, and Fowler was recognized by Time as one of the "Silence Breakers" who ignited the #MeToo movement. Here, she shares her full story: a story of extraordinary determination and resilience that reveals what it takes--and what it means--to be a whistleblower. Long before she arrived at Uber, Fowler's life had been defined by her refusal to accept her circumstances. She propelled herself from an impoverished childhood with little formal education to the Ivy League, and then to a coveted position at one of the most valuable companies in the history of Silicon Valley. Each time she was mistreated, she fought back or found a way to reinvent herself; all she wanted was the opportunity to define her own dreams and work to achieve them. But when she discovered Uber's pervasive culture of sexism, racism, harassment, and abuse, and that the company would do nothing about it, she knew she had to speak out—no matter what it cost her.
