Cogman's early years were steeped in the world of books. A voracious reader from a young age, she consumed a wide range of genres, including fantasy, science fiction, and historical fiction. This early exposure to diverse narratives laid the foundation for her own storytelling abilities and instilled a deep appreciation for the power of imagination and world-building, core elements of her later works. Her interest in history, specifically medieval and early modern periods, also began to blossom during this formative time.

Cogman pursued higher education, likely studying relevant fields such as history or literature. This period was crucial in honing her research skills and providing a deeper understanding of the historical contexts that often influence her fiction. Her academic background likely contributed to the meticulous detail and intellectual rigor that characterize her writing, providing a rich and plausible backdrop for her fantastical narratives. The influence of classical literature and mythology are also likely influences from her University Education.
