Rolling in the Deep reimagines mermaids as apex predators of the deep ocean. The novella Rolling in the Deep (2015) follows a mockumentary crew searching for mermaids who discovers the creatures are horrifyingly real. Into the Drowning Deep (2017) expands the story into a full-length novel, sending a scientific expedition back to the same waters with full knowledge of the danger.
The series, written as Mira Grant, combines marine biology with horror, creating mermaids that are beautiful but utterly lethal. Into the Drowning Deep received particular praise for its diverse cast of scientists and its treatment of the mermaids as genuinely alien creatures rather than fantasy beings.
