The Record of Currupira

What if the Martians came to Earth fifty thousand years ago, and left records? James Dalton, a linguist specializing in Martian archaeology, becomes obsessed with a terrifying recording: the voice of something the Martians called the Currupira. When his colleague Dr. Thwaite vanishes into the Brazilian rainforest chasing this ancient evil, Dalton must follow into a world where the line between human myth and extraterrestrial reality blurs. Abernathy weaves linguistics, adventure, and genuine dread into something unique: a story where the oldest threats aren't human, and the deepest fears have names we forgot we already knew. The climax is a confrontation with something that existed before history, before language, before humanity itself.
