Meet Phoebe. She's eleven years old and desperate to escape the boring island where she lives.

Enter the Argonauts - a crew of so-called heroes on a quest to grab the golden fleece.

Before Phoebe can think better of it, she boards the ship and stows away on the Argo. But the Argonauts have their work cut out. From attacking harpies to deadly whirlpools, giant sea monsters to skeleton armies, there is peril at every turn. Fortunately the Othernauts are on hand - though with Phoebe's unhelpful prophecies, Perry's unreliable shape-shifting skills and Cora the siren's headache-inducing singing, it's not quite clear exactly how much help these kids will be . . .

Do the Othernauts have what it takes to get the Argo and its motley crew back to safety in one piece?

About the Author

Macha (short for Marie-Charlotte) Yao is a children’s illustrator and designer originally from France, now based in West Yorkshire with her family. Her vibrant, 90s-inspired style bursts with bright colors and characters full of personality, from adventurous animals in sneakers to spirited kids on a mission. Macha firmly believes that children’s books should empower young readers, inspire self-confidence, and always include a good dose of humor—because life shouldn’t be taken too seriously.

When she’s not holding a pencil, you’ll find Macha dancing on her longboard with an indie folk tune in her headphones or relaxing with a...matcha bubble tea.
