From the publisher:
In a bizarre sci-fi western world, where cyborg bounty hunters ride dinosaurs and magical skulls give powers to alien outlaws, the notorious Doolin brothers seek a stash hidden in a heist gone sour. And the key to finding it might be the young girl they recently rescued from a parallel dimension-- a girl with uncanny skills with a pair of revolvers! The first volume in a gonzo new adventure series from the wild imagination of Captain Artiglio.
