A trilogy in the making

The Forgotten Prince begins at the end of an era. With the death of Brian Boru at the Battle of Clontarf, Ireland is left without its defining figure — and with unanswered questions about what follows.

Book 2

The story turns to an unexpected son, drawn into events larger than himself, forced to navigate power, loyalty, and legacy beneath the shadow of a father whose name reshaped the island.

Book 3

The trilogy will end many decades after the Battle of Clontarf, which traverses the continent of Europe.

The Invasion Island Storyworld

The Forgotten Prince is not only the opening volume of a trilogy, but the point of entry into the wider Invasion Island storyworld.

The project is shaped by a background in filmmaking and acting, and by a long-standing interest in how history is experienced rather than recorded. While the ambition to see these stories on screen is natural, the priority here is to create enduring narrative work—stories strong enough to stand on their own.

The trilogy is written through a cinematic lens, focusing on characters who emerge vividly from Ireland’s history, mythology, and folklore—figures whose names and deeds have endured in the Irish consciousness long after their time.

What begins here is an attempt to give those lives shape and continuity, not as isolated legends, but as part of a wider story about power, belief, invasion, and memory in Ireland.
