Otto Kessler is seven years old, and he knows more about the ocean than most adults.
He knows the deepest point on Earth is almost seven miles down. He knows we've mapped more of the moon than the ocean floor. He knows that down in the dark, where sunlight never reaches, things glow.
What he doesn't know is what's waiting for him at the bottom.
When Otto joins his mom - a marine biologist - on a research expedition to one of the deepest trenches on Earth, he expects to see strange fish and underwater volcanoes. He expects to press his face against the glass and watch the light disappear.
He doesn't expect the ocean to notice him back.
Four Miles Down is a deep-sea adventure about the biggest mystery on our planet - the one right beneath the waves. Featuring real ocean science, uncharted waters, and a discovery that changes everything Otto thought he knew about what's alive down there.
