Carbonel is a magical fantasy story by Barbara Sleigh. This is the story of a cat, a broomstick and an ordinary schoolgirl called Rosemary. She bought them both in the market, quite cheaply.
Of course, neither the cat nor the broomstick were just what they seemed, and they turned up just when Rosemary badly needed something nice to happen to her. A good cat is apt to be independent, so she did not have things all her own way, and as Carbonel proved to be a Royal cat in a very special sense, that was understandable. Between the cat and the broomstick, Rosemary picked up some useful spells and magic, and the adventures they brought about turned a dull-looking holiday into one long to be remembered for its unexpected excitements and rewards.
Carbonel is reissued in the 'A Puffin Book' series of Puffin children's modern classics.
