About Rolling in the Deep
A reality-TV stunt becomes a voyage into terror in Rolling in the Deep, Mira Grant’s razor-edged aquatic horror novella. When the Imagine Network sends the cruise ship Atargatis into the Mariana Trench to film a sensational documentary about mermaids, the mission is meant to be half science, half spectacle. The crew expects staged encounters, dramatic footage, and easy ratings. What they find instead is proof that some legends survive for a reason — and that the ocean’s darkest depths are home to predators humanity was never meant to meet. Blending found-footage unease, scientific curiosity, and claustrophobic sea-bound dread, Grant turns a familiar myth into something vicious, intelligent, and terrifyingly plausible. Grim, fast-paced, and unrelenting, Rolling in the Deep is a chilling tale of exploitation, hubris, and the monsters waiting below the waves.
