'Follow the big blue'. That was the last thing Cam's father said to him.
Cam follows Big Blue - everybody does on the island of Cetacea. Their lives take place within his rules, delivered to them by enigmatic whale-talker, Byron Vos.
Byron was once a marine scientist but is now organizing an epic clean-up operation to revive the ocean after centuries of human greed and neglect. And yet Cam wonders if there is a more complex truth.
A truth that may be connected to his father's disappearance. Cam's quest to understand Big Blue leads him to new friends and shared adventures - but the truth, when he finds it, is more dangerous than ever he could have imagined.
