Polly Plum dreams of being a brave adventurer, but her father has other ideas. He wants her to settle down and become Mrs Smellbad-Frown. That won't stop Polly though! 

Join award-winning author Jonathan Sellars as he tells Polly's story as she sets sail from Greenwich in search of adventure. You'll meet singing pirates, a boastful ghost, and a very, very hungry walrus along the way. 

Watch out adventure, here comes Polly!

Meet the speaker

Jonathan Sellars is an author and poet based in Greenwich. He adores stories and the power they hold. 

Jonathan also writes poetry for children. He has performed these on BBC London, at literary festivals. Poetry for him is simply about the joy that can be had with words; the way they sound, the way they look on a page, the way they make you feel. Further to this, research by the National Literacy Trust has highlighted the significant benefits poetry brings to children’s lives in the way it fosters creativity, supports mental wellbeing, and encourages self-expression.
