Don't let murder get in the way of immortality.

Laelius Calvus wants to start his own religion. Something grandiose and profitable, without being weighed down by minor details such as which god to worship. The only things standing between him and a temple-funded expenses account are a disappearing corpse, a runaway niece, a rival priest selling dodgy funeral insurance and a father who, gods forbid, wants Calvus to succeed in life.

As a glassblower's apprentice living on the outskirts of the ancient Roman city of Londinium, Calvus has a choice: leap into a murky world of blind faith and ulterior motives, or risk being revealed as a charlatan and lose the chance for gaining divine riches and a comfortable bed.
