"Even angels have to make a living these days."

With this dry observance Peter Darbyshire introduces us to Cross, a man who has lived thousands of years, though he'd prefer not to have, and who is now hunting angels in a Barcelona filled with tourists, phone cameras and deep mystery. The Mona Lisa Sacrifice is a layered supernatural thriller, filled with history, magic and beloved characters. When an angel promises to deliver Judas, a forgotten god of a forgotten people, to Cross for revenge if he can find the real Mona Lisa, a cascading set of mysteries involving a sisterhood of gorgons, Alice from Alice's Adventures in Wonderland, Morgana le Fay and renegade angels is set in motion. Everything hangs in the balance. Even the fate of the world.
