When Leah comes back home to her wife, Miri, she is not quite herself.

Leah, a marine biologist, was supposed to go on a routine expedition in the ocean for three weeks. She comes back six months later. 

Told in duel narratives with Miri trying to adjust with Leah’s new eccentric behaviors and Leah’s ponderings of what happened to her under the sea. And what did happen to her??

This is one of the strangest and haunting books I’ve read this year.
