What readers sayAbout The Mountain in the Sea.

JB Jamal B.2 days ago★★★★★

The octopus's alien intelligence felt genuinely weird and wonderful. Made me realize how little we understand about consciousness itself.

SY Svetlana Y.1 week ago★★★★★

The ocean setting gave the story a claustrophobic beauty. When the octopus finally communicates, it's both beautiful and terrifying.

JW Jake W.2 weeks ago★★★★☆

Inventive worldbuilding and cool scientific concepts. Some philosophical sections dragged a bit, but the climax redeemed it.

ML Mei L.2 weeks ago★★★★★

The relationship between the researcher and the AI challenged everything I thought about intelligence. Profoundly unsettling.

AH Arne H.3 weeks ago★★★★★

A first contact story told from the ocean. The ending about what it means to meet the truly alien left me speechless.
