Remarkably Bright Creatures

"Jennifer Ayawa is a heartbroken cryptozoologist with a single, fading passion: pursuit of the Miliagyaur, a legendary tentacled monster that dwells at the bottom of the ocean. That's hogwash, of course. Ayawa's friends and family are certain she's wasting her time, but her obsession is about to pay off in the form of a life-changing discovery, one that will either heal her broken heart or destroy her altogether. It all begins with a dive she never should have taken."
