When the Russian invasion of Ukraine began on February 24, 2022, Ukraine's relatively young and inexperienced president, Volodymyr Zelenskyy, immediately marshalled his nation's military forces. From that moment forward, Zelenskyy has displayed remarkable courage and resolve in the face of a brutal and larger, more well-equipped foe. He speaks nightly to his people, millions of whom have been displaced by the war. He visits Ukrainian soldiers on the frontlines. He reaches out to nations worldwide for weapons and other aid. He uses social media to combat Russian lies. This book explores how Zelenskyy, a former comedian and television personality, has become an unlikely hero—to his people and to the world.
