They said giants were only legends, but the truth is they are real.
A rare genetic mutation. A centuries-old mystery. A journey that spans folklore, science, and family.
In Search of Giants: The Quest to Find the Genetic Giants of Northern Ireland is a gripping blend of medical mystery, personal memoir, and Irish history. It follows Colleen Snyder, the first person in the United States identified with a rare Irish genetic mutation that causes gigantism, as she meets fellow giant Brendan Holland from Co. Tyrone and uncovers a forgotten legacy.
What's inside:
- Rare disease and genetic discovery - Learn how a mutation in the AIP gene causes life-threatening gigantism and how it can remain undiagnosed in many for years.
- True medical mystery - Explore the story of Charles Byrne, the 18th-century Irish giant whose body was stolen-and how his DNA cracked open centuries of scientific secrets.
- Irish history and folklore - Dive into the legends of Fionn Mac Cumhaill and the rich mythos of giants in Ulster, where fact and folklore intertwine.
- Personal journey and identity - Follow Colleen's quest from a pandemic-era Google search to her discovery of ancestral ties, newfound Irish kin, and a global network of others with the same mutation that caused their gigantism.
- Genetic genealogy and ancestral connections - See how London researcher Professor Márta Korbonits traced this mutation back 2,000 years to a hotspot between Lough Neagh and the Sperrin Mountains, linking families from Mid-Ulster in Northern Ireland to Scotland, Canada, Australia, and beyond.
- Interviews and lived experiences - Hear the voices of modern-day giants, including co-author Brendan Holland, as they reflect on what it means to carry this condition, this history, and this legacy.
