Looking for a book I checked out several times from an elementary school library in the mid-80s (not sure how old the book was). It was NOT the Verne story but was about a group of people who walked across the bottom of the ocean between the continents. They had some sort of tanks that allowed them to eat and breathe underwater.
Mercycle by Piers Anthony? “An alien from an alternate reality recruits five people on an exciting mission to save the Earth from a meteor strike. The alien’s advanced technology allows the intrepid humans to breathe underwater as they embark on a wondrous journey through the ocean.”
Thanks sueelleker – sounds interesting too! Cathy nailed the book I remember though.
