What’s it about?
The story.
Ever since her father was lost at sea, Sophia has drifted, unhappy and adrift, around Aqualand, the marine theme park her dad and uncle dreamed up together. Then her world turns upside down when an aquanaut, a battered diving suit, breaks into the park's research lab, and Sophia discovers that inside it lives a crew of four gloriously goofy sea creatures piloting the suit as one. As she gets to know her unlikely new friends, Sophia realises that Aqualand has drifted far from her father's vision into something darker, a place that puts profit above the marine life it was meant to celebrate. Determined to put things right, Sophia and the aquanaut crew hatch a plan to free the park's captive animals before it's too late. From Caldecott Medalist and National Book Award winner Dan Santat comes a whimsically adventurous, deeply felt graphic novel about grief, family, friendship and standing up for the natural world.
