Decoding the Unicorn: A New Look at Dag Hammarskjöld
In the shadow of the Cold War, one man stood alone.
Dag Hammarskjöld was the world’s most unusual introspective but unflinching, poetic yet pragmatic. As Secretary-General of the United Nations during one of the most volatile eras in modern history, he navigated emergencies like the Suez Canal and the Congo Crisis with moral clarity and an iron spine. He made powerful enemies who preferred their wars profitable and their “peacekeepers” obedient. But that wasn’t Dag.
This is not the Hammarskjöld of textbook footnotes or dusty academic tomes. This is the Dag few ever saw—fiercely intelligent, often misunderstood, wryly funny, quietly revolutionary, and profoundly warm beneath his composed exterior. In Decoding the Unicorn, award-winning author Sara Causey offers a portrait unlike any part biography, part soul-deep conversation with a man whose legacy still resonates.
Drawn from rare materials, emotional insight, and a creative bond that transcends time, this book doesn’t just tell Dag’s story—it invites you to feel it.
For readers who crave substance over spectacle, courage over cynicism, and meaning over noise, this isn’t just a book. It’s an intriguing, gripping, and unforgettable encounter.
Some books are told. This one is lived.

This biography shares the story of the life of a truly great man of the past. Instead of a boring account from history, this biography immediately had me interested from the first few pages. The story flows easily and as each part of Dag Hammarskjold’s life is revealed, Ms. Causey leaves the reader wanting to know more, to learn about this man who, for many, was previously unknown.
Dag Hammarskjold, the second Secretary of the United Nations was a Swedish Diplomat who, throughout his life, served his own and the global community. Unfortunately, this great diplomat and man who sought to bring peoples together died tragically in 1961. Ms. Causey’s writing shines light on the life and work of this great man from the somewhat recent past.
For anyone who has an interest in history and wants to learn about a great man and diplomat, who history has passed by, this biography is one that I strongly recommend.

Dear Politicians Everywhere, PLEASE READ!
What a refreshingly optimistic outlook by a politician many Americans may not know much about (including myself, until just recently!)
I am not typically a big political biography reader, so while I did expect to learn a good bit, I was pleasantly surprised at how enjoyable this book was as well as educational. The author perfectly balanced her storytelling of Dag’s life by sharing a healthy mix of both facts regarding his career and life events as well as insight into his personal life, hobbies, and feelings.
I found myself using the “highlight” feature on my kindle more than I ever have with any other book to date. So many of the quotes in this book (especially those from Dag’s personal journals) are downright inspiring. I plan to reflect back on these myself. If more people shared some of the same political, moral, and intellectual point-of-views as Dag, the world would very likely be a better place.
Mr. Hammarskjöld, may you rest in peace. Thank you for your years of service to our world and your faith in humanity.

Dag Hammarskjöld’s legacy is nothing short of remarkable, and even greater is the man behind the myth. Author Sara Causey impressively presents Hammarskjöld in biography form while, with tremendous insight, revealing the complete motivations and “self” of the man who strived for peace among nations with a pure, unique humanitarian approach.
As a reader, most surprising about Decoding the Unicorn is how empowering it is to introverted and extroverted audiences alike. Both of these traits offer equal strengths, but in a world dominated by the “loud” and more frequently misunderstanding of the introspective, what better way to break down trait barriers than to look at the legacy of an in-his-element, eminent introvert in Hammarskjöld. After learning about Hammarskjöld’s life and reflecting, one reckons that the man should be used as a leading example more when discussing introversion. Causey does an incredible job showcasing how he utilized his strengths as an introvert to the utmost potential, and with the utmost impact.
In the political landscape, Hammarskjöld stands out in a sector more often associated with extroversion—and stand out he does due to his empathy, quiet (yet effective) ways in navigating as a politician, and for his achievements and enduring ideas about humanity. I greatly enjoyed this read. For readers interested in Hammarskjöld, the biography genre, and even those seeking reads on social traits and introversion, I would highly recommend Causey’s Decoding the Unicorn. In addition to getting to know Hammarskjöld as closely as a reader can, I walk away with much insight on myself and others and am better for it.

Causey masterfully explores one of the 20th century’s most enigmatic and influential figures, Dag Hammarskjöld, in his latest book. She portrays Hammarskjöld as an introverted leader who flourished in a world shaped by extroverted norms. The book delves deeply into the qualities that made Hammarskjöld a “unicorn” among global leaders: his deep introspection, poetic sensibilities, and steadfast commitment to peace and ethical governance. The narrative seamlessly weaves Hammarskjöld’s Swedish upbringing with his pivotal role in Cold War diplomacy. The inclusion of Hammarskjöld’s writings from Markings adds an introspective layer, allowing readers to glimpse the profound personal philosophy that guided his actions.
Causey’s depiction of Hammarskjöld’s quiet diplomacy—an approach rooted in listening, collaboration, and principled decision-making—offers timely insights for today’s leaders navigating a polarized world. While honoring Hammarskjöld’s legacy, Causey also confronts the controversies of his career and the lingering mystery of his death, presenting a multidimensional figure whose imperfections underscore his humanity. Causey’s portrayal of Hammarskjöld leaves readers with a profound understanding of leadership shaped by principle, introspection, and quiet resolve, offering timeless lessons for a fractured world. An intimate and balanced perspective on a figure often shrouded in myth and misunderstanding, this is essential reading for anyone interested in history, international relations, or the transformative power of ethical leadership.

"Decoding the Unicorn: A New Look at Dag Hammarskjöld" is an exceptional biography that celebrates Dag's journey as a powerful but reserved diplomatic leader and humanitarian. This book is a fresh take on history that really brings to life his legacy in a way people (especially introverts) can understand and relate to.
From his childhood exploring castles and nature to his deep Christian faith, family ties, and dedication to global peace, I can see where his thoughts and decision-making comes from. Just like a Unicorn, he saw himself as being different from other men by the choices and sacrifices he made (such as celibacy in order to fully dedicate himself to his work).
His journal entries illustrate how he enjoyed his solitary time behind-the-scenes and tried to stay away from the press and any gossip or drama. His writing was poetic and centered around his deep faith and devotion to God.
He worked tirelessly throughout his life, from teaching political economics to becoming a Swedish Civil Servant, and later becoming the second Secretary-General of the United Nations. It's amazing how much he achieved in his life. He even won the Nobel Peace Prize (after his death). He displayed a lot of empathy, gratitude, self-control, and humbleness.
His legacy will continue to live on through this book, giving him the recognition he deserves. Many people will benefit from reading this book by learning what it takes to become a good leader and how being reserved and empathetic can be a real strength. I'm sure he would really appreciate this book.

This is a half-novel/half-biography of Dag Hammarskjold, the second Secretary General of the United Nations.
He was an introverted kid growing up in Sweden. He was very bookish, and loved spending time outside. Rising through the ranks of the Swedish Civil Service, Dag found himself as part of the Swedish delegation to the UN. The first Secretary general, a Norwegian named Trygve Lie, resigned for personal reasons. Dag was something of a compromise candidate. He didn't want the job, but he accepted it.
He was dropped in the middle of a media hurricane. There were constant accusations that he didn't have the guts for the job. The press seemed to obsess about what he thought of American women, or if he was dating anyone. He hated talking to the press, but understood that it was part of the job. Lie, his predecessor, loved the press (and was something of a jerk to the staff).
Dag improved morale by intentionally meeting every member of the staff, from the top floor to the basement. He also threw out the FBI, who were all over the building, looking for commies everywhere. He felt that diplomacy was not quick, even though the press was very impatient for results.
This book does an excellent job exploring the life of a person unfamiliar to most people. It is well worth the time.

Decoding the Unicorn: A New Look at Dag Hammarskjöld presents a carefully researched and interpretive examination of one of the twentieth century’s most consequential international civil servants. Rather than offering a comprehensive cradle-to-grave biography, Sara Causey situates Hammarskjöld within broader intellectual, political, and ethical frameworks, emphasizing the role of temperament, faith, and restraint in diplomatic leadership.
The book is particularly effective in its treatment of introversion and quiet diplomacy as functional leadership assets rather than personal idiosyncrasies. Causey integrates historical context with narrative analysis, drawing from primary and secondary sources to illuminate Hammarskjöld’s approach to governance, mediation, and moral responsibility during periods of geopolitical instability.
Written in an accessible yet serious scholarly voice, this work will be of interest to readers in international relations, leadership studies, and modern political history. It offers a valuable reframing of Hammarskjöld’s legacy while contributing to contemporary discussions about leadership styles beyond performative authority.

Decoding the Unicorn opened the book on the story of Dag Hammarskjöld. I wasn't even aware of who this man was before I read this book and now, I think everyone should know who he is. Dag was the Second Secretary General of the United Nations, and I believe one of the reasons it exists today. He dedicated his life to public service and peace in the world. The author truly introduces us to who this man was as a person, not just the public figure. Through anecdotal stories she shows us who he really was. She shares not only the key moments in his role within the United Nations, but also the private moments, the little moments that introduce us to who he was as a man. She walks us through his introverted nature and how it was key to his diplomacy. Using his journal and speeches she bridges the gap of his private life and public persona. Dag was a key person to the success of the UN, and I think everyone should read about his life!

The Legacy of a Gentle Giant
This book is not just a biography—it’s a soul-stirring reminder that true leadership doesn’t shout. Dag’s story, as told by Sara Causey, is deeply human, tenderly told, and emotionally resonant. If you’ve ever felt out of place in a loud world, Decoding the Unicorn feels like a whispered reminder: your quiet strength matters.

I enjoyed this book very much. Dag was an amazing person and this book held my attention easily. Having read other biographies about Hammarskjold, I was impressed with how the author actually told his *story.* This is not a rehash of facts and dates; you can feel Dag's heart and soul.
