Navidad and Matanza by Carlos Labbé (2014, Open Letter, Trade Paperback), like new. Orders normally ship within 24 hours.

it's the summer of 1999 when the two children of wealthy video game executive Jose Francisco Vivar, Alicia and Bruno, go missing in the beach town of Matanza. Long after their disappearance, the people of Matanza and the adjacent town of Navidad consistently report sightings of Bruno -- on the beach, in bars, gambling -- while reports of Alicia, however, are next to none. And every story and clue keeps circling back to a man named Boris Real...

At least that's how the story -- or one of many stories, rather -- goes. All of them are told by a journalist narrator, who recounts the mysterious case of the VIvar family from an underground laboratory where he and six other "subjects" have taken up a novel-game, writing and exchanging chapters over email. while they wait for the fear-inducing drug hadón to take its effect, and for their uncertain fates.

A literary descendant of Roberto Bolaño and Andrés Neuman, Carlos Labbé's Navidad & Matanza is a work of metafiction that not only challenges our perceptions of facts and observations, and of identity and reality, but, most importantly, of basic human trust.
