Bipolar Sunset is a powerful and deeply personal memoir that traces an extraordinary journey across continents, careers, and inner struggles.

From humble beginnings in post-war Yorkshire to a high-stakes career in the international oil and gas industry, David Summerville's life unfolds through some of the world's most challenging and volatile environments, including conflict zones, extreme working conditions, and culturally complex regions. But beyond the adventure and global exposure lies a more profound story, one of emotional highs and lows, personal challenges, and the psychological toll of living a life constantly pushed to its limits. Through vivid storytelling and honest reflection, the book captures not only the external risks of the profession but also the internal battles that shape identity, resilience, and purpose.

From navigating early life influences and formative experiences to confronting uncertainty, isolation, and pressure in unfamiliar territories, this memoir offers a rare and unfiltered look into a life driven by ambition, curiosity, and endurance.

Bipolar Sunset is more than a travel or career narrative, it is a compelling story of survival, transformation, and the search for balance in a world defined by extremes. It speaks to anyone who has faced adversity, sought meaning, or dared to step beyond the ordinary.
