In the shadow of ancient Rome, a 2,000-year-old conspiracy is about to rewrite reality itself...

For disgraced classics professor Marcus Whitby, life is a series of minor humiliations and unpaid alimony. But when his detective friend summons him to a murder at the Museum of Classical Antiquities, he is plunged into a world of impossible secrets. The victim lies arranged in perfect imitation of Julius Caesar's assassination, and the only clue is a cryptic Latin message: "The Aurelii Remember."

As the body count rises—each murder a chilling reenactment of a pivotal death in Roman history—Marcus finds himself hunted by the Aurelian Society, a powerful cabal claiming direct descent from the Caesars who believe their time to rule has come again.

With the help of Zoe, a brilliant but paranoid graduate assistant with her own hidden past, Marcus discovers that the key to the conspiracy lies in a series of innocuous garden gnomes. These aren't just decorations; they are ancient communication devices, part of a cipher system that holds a terrifying power. But this is no simple code. The Aurelians are not just preserving history—they are preparing to weaponize it. Their plan, "The Ascension," is a ritual designed not merely to seize power, but to fundamentally reshape the laws of physics and open a gateway to a reality beyond human understanding.

Now, Marcus must race against a countdown two millennia in the making. Can he and his allies stop the ritual before the "Thirteenth Hour" arrives, or will they become the final sacrifice in a ceremony that will see reality, and history itself, collapse?
