25 Summers by Stephan Schafer is a delightful, uplifting self-help fable that has been the success story of German publishing this summer - a surprise bestseller which has sold over 130k copies since its release in March 2024. In a simple yet deeply impactful narrative, the book tells the story of a man whose formal and career-driven life is transformed through an unexpected meeting - and fast developing friendship - with a potato farmer named Karl.Their enthusiastic and charming conversations, set against the pastoral backdrop of the German countryside, are rich with real-life wisdom and inspire the central character to slow down, live in the moment, and reconnect with life's most important values. Reminiscent of warm, uplifting philosophical fables like The Alchemist and Tuesdays with Morrie - this story is resonating strongly with readers of all ages, from young female readers to personal development readers in midlife, offering a gentle reminder to find peace, connection, and joy in the everyday.
