Neon Depths

Eleven-year-old Coral lives on a floating research platform in the Pacific Ocean. When she takes her homemade mini-submarine on an unauthorized dive, she discovers a hidden underwater city powered by bioluminescent technology — and its kid inhabitants need her help to save their dying light source.

Your name is Coral, and you live on Research Platform Zephyr, a floating science station in the middle of the Pacific Ocean. Your mom is a marine biologist who studies deep-sea creatures, and you have spent your whole life surrounded by saltwater, sonar screens, and glowing jellyfish samples.

'Most kids have backyards,' you like to tell people. 'I have the entire Pacific Ocean.'

Your favorite thing in the world is the mini-submarine you built from spare parts in the station workshop. You call it the Firefly because of the bright yellow headlights you bolted onto its nose. It took you six months to build and it is, without question, the coolest thing anyone on this platform has ever made.
