My Favorite Scar by Nicolás Ferraro

A teenage girl and her gangster father embark on a road trip toward revenge in this award-winning coming-of-age Argentinian noir.
Fifteen-year-old Ámbar has never known any parent other than her father, Víctor Mondragón, nor any life other than his. On any given Friday night, Ámbar longs to be at the arcade or a rock concert, but she's more likely to be patching up Víctor's latest bullet hole in a dingy motel or creating a new set of fake identities for the both of them.
When a tattooed mercenary kills Víctor's best friend and vows that Víctor is next, father and daughter set off on a joyride across Argentina in search of bloody retribution. But Ámbar's growing pains hurt worse than her beloved sawed-off shotgun's kickback as she begins to question the structure of her world. How much is her father not telling her? Could her life ever be different? And will she survive long enough to find out?
It's kill or be killed in this gritty, devastating coming-of-age thriller from the king of Argentine neo-noir.
