What’s it about?

The story.

Life is changing fast for Cymbeline Igloo. It used to be just him and his mum; now the house is full of her new partner and his children, and Cym isn't sure he likes it one bit. Then he comes home to find the place has been burgled - by thieves who seem strangely interested in his toys, though they've missed Not Mr Fluffy, his Bear of Most Extreme Importance. Meanwhile, a girl called Jessica pulls a filthy, bedraggled teddy out of a river while playing with her family, with no idea it will change everything for ever. Told in turn by Cym and Jessica, the two find themselves swept into a mystery that spans decades and threatens both their families. Adam Baron's third Cymbeline novel keeps the trademark laugh-out-loud voice while tackling a blended family, a grandfather's illness and the hard business of growing up. Warm, funny and full of heart, with a story that will have readers laughing one minute and welling up the next.

Why it lands

Why they love it.

Why kids love it

Cym's home is suddenly full of step-siblings he didn't ask for, his toys are being stolen, and a mystery teddy is turning two families upside down. Kids love the twin narrators, the daft humour and the puzzle that keeps them guessing right to the end.

  • Being a detective
  • Family belonging
  • Being understood finally
  • Making a difference

Why parents love it

Baron captures the wobble of a family reshaping itself - new partner, new siblings, an ill grandfather - with warmth and wit rather than worthiness. The dual narration is clever, the voice is a joy aloud, and it opens gentle conversations about change.

  • Shared humour
  • Conversation starter
  • Great writing

Benji Davies

Illustrator · United Kingdom

Benji Davies is a British author-illustrator best known for The Storm Whale (2013) and its sequels The Storm Whale in Winter and Grandad's Island, quietly emotional picture books with a distinctive painterly, slightly retro visual style and a Scandinavian-fishing-village setting that has become one of his signatures. Davies's work tends to land in the gentle-but-serious end of the picture-book market, often handling loneliness, family change, loss and the comfort of small communities. He also illustrates for other authors (the Bizzy Bear board books) and works in animation. A reliable bedtime and gift-shelf picture-book maker for ages 3–7, with particular strength in emotional weight done lightly.
