In Hope in Action, Sanna Marin takes readers on the extraordinary journey of her trailblazing career and shares her vision for a new kind of leadership. When she became Prime Minister of Finland at just thirty-four years old, Marin was the world's youngest serving prime minister at the time, captivating the world's attention with her progressive ideas and her boldness amidst major crises. Marin's story is one of resilience and hope. The first in her family to attend university, she broke barriers to become a global icon of progressive leadership. Her time as Prime Minister saw historic milestones. During Marin's term (2019 - 2023), she led Finland through the COVID-19 pandemic, and her government implemented many progressive reforms addressing climate change, social justice and equality. She helped the country navigate neighboring Russia's devastating full-scale invasion of Ukraine, and Finland's rapid joining of NATO - the swiftest entry for any country in the alliance's history. Through vivid retellings of her experiences, Marin shares how she overcame significant political challenges, and how she coped with her personal life becoming public, like in an incident that sparked a media frenzy and prompted women including Hillary Clinton and Alexandria Ocasio-Cortez to express their support for Marin. Hope in Action is much more than a memoir-it's a call to action. Marin urges the next generation of leaders to bring their full selves to the job. Her story is an empowering testament to the opportunities we have to affect real change in our worlds.
