An immortal love story with turbulence, tailplay, and one very bad archdemon.

Kalili is a demon. Faith is an angel. They've been in love for over a thousand years, dodging divine mandates, demonic grudges, and the occasional awkward prophecy. All they want is a quiet anniversary trip to Rome.

Instead, they get jet engines, flirtatious stewardesses, an unexpected exorcism, and a vintage aircraft full of inconvenient witnesses.

Set in 1952 during the dawn of the jet age, A Roman Holiday is a supernatural romantic adventure with snark, seduction, and the kind of chaos that follows when two Immortals try to have a normal life (for highly subjective definitions of "normal").

If you're looking for queer joy, ancient powers in stylish outfits, and a love story that spans millennia with a wink and a growl?this is your boarding call.

Welcome to the Cassidyverse. Please keep your seatbelt fastened. Things are about to get wild.
