When Cork academic Seán kills an annoying fly and examines it under his flatmate's microscope, he makes a discovery that will shatter everything he believes about reality. What he sees in that tiny specimen launches him into a labyrinth of historical conspiracy, ancient texts, and dangerous secrets that powerful people have killed to protect.

As Seán and his fellow researchers dive deeper, they uncover evidence that this same discovery was made centuries ago by some of Europe's greatest minds—Galileo, Milton, Newton — only to be ruthlessly suppressed. From the scientific academies of 17th-century Amsterdam and Paris to the corridors of power in Renaissance Rome, a hidden truth has been carefully buried, one that challenges our understanding of human civilisation itself. But knowledge this profound comes at a price.

As the mystery deepens, Seán realises that some secrets have guardians who will stop at nothing to keep them hidden. In our age of deepfakes and social media deception, EL asks the most urgent question of our time: who controls reality?
