Long before he became a legend, Nicholas Santa was an Arctic explorer fighting to survive the frozen edge of the world. When a violent polar storm tears him from his family, Nicholas stumbles upon something impossible beneath the ice: a hidden civilization of elves, ancient machines, and secrets older than recorded history. What begins as survival quickly becomes initiation into a world where myth and technology are indistinguishable. As tensions rise between isolationist elven elders and a dangerous rebel known as Jack, Nicholas is drawn into a conflict that threatens to erupt into open war between worlds. To endure, he must confront altered reindeer, intelligent snow beings, and technology so advanced it borders on the divine, all while discovering that the choices he makes will echo far beyond the ice. Claus: Legend of the Fat Man is a sweeping epic fantasy that reimagines the origin of Santa Claus as myth, not folklore. Darker, richer, and more ambitious than traditional holiday tales, this is Christmas mythology for readers who crave deep worldbuilding, high-stakes adventure, and the birth of a legend forged in snow and fire. Book One of the Claus Universe series.
