Agnes Triptoes is back—and the world is in danger of becoming unbearably beige.
A new Agnes Triptoes adventure by Sarah Tucker
Agnes is in her final year at Homerton College, and everyone wants to know what she plans to do next. She has more interests than she can count and no desire to squeeze herself into somebody else’s idea of a sensible career. An unusual internship at SYM seems like the perfect place for someone who thinks differently.
Then Agnes discovers that SYM has a far more sinister plan: to flatten people’s emotions and make them easier to control.
To stop it, she joins forces with a Scottish badger, an electrically charged squirrel, a monocled otter, a clairvoyant hen, a meticulous tortoise, a theatrical raven and one particularly cryptic hedgehog. Their mission takes them into the Ministry of Illusions, where the rules make very little sense and following them could be the worst mistake of all.
Can Agnes and her unlikely team outwit SYM before the world forgets how to feel?
Full of talking animals, improbable plans and inventive humour, Size Eight is an adventure about curiosity, courage and finding your own path.

Why readers will enjoy it
Agnes Triptoes facing her biggest and strangest mission yet
Seven talking creatures with wildly different talents
Absurd inventions, daring plans and a Ministry full of surprises
A story about emotions, imagination and thinking for yourself
Meet the team
Pilkins the Scottish badger brings strategy. Moozle the squirrel brings electrical chaos. Beryl the monocled otter knows how to infiltrate a building, while Lady Millicent Fowl has a talent for unusual predictions. Kevlar the tortoise likes a plan, Reggie the raven likes an audience, and Cuthbert the hedgehog sees possibilities that others miss.
Whether they can agree on how to save the day is another question.
For curious young readers
The Size Eight pitch recommends the story for readers aged 8–12 who enjoy talking animals, imaginative adventures and clever humour. Readers who know Agnes from Size Six and Size Seven will recognise parts of her earlier story, while new readers can join her on this adventure.
