Luminous, a flashlight fish, and her friends are on an adventure through strange and wonderful places in the deep sea. They encounter creatures such as sticklers, jellybells, and craggles as they make collections and map their journey, exploring new worlds and discovering exciting things about "the pressure." Along the way, Luminous learns some surprising things about her surroundings and believing in herself.
