Artist Victor Santos posted the following process art piece to his Twitter account today. The piece is from the upcoming Dark Horse graphic novel Polar Vol 3: No Mercy For Sister Maria, a 160 page noir / action hardcover shipping in August. It is the third volume in the webcomic collection.
A mob boss discovers his young wife, Maria—seeking an escape from a life of organized crime—has been hiding in a nunnery in rural Europe. Sullivan, a mobster who's been tasked with bringing the woman back home, is actually an undercover FBI agent seeking Maria as a star witness in his case against the don. But when Maria's whereabouts leak and mobsters, mercenaries, and hit men converge on the convent in the hopes of collecting a reward for Maria, they turn holy ground into a battleground.
