Gemma Kaliski and Amy Ford have been best friends for years. They share the same interests and sense of humour - and the same contempt of tall, thin blondes, whose only talk is of boys and fashion. Now almost over night, Amy has changed: she's into salads and diet Coke; she's got a new hairstyle, wardrobe and set of friends. Gemma - short, dark and full of figure - finds herself part of a group of unglamorous oddballs, nicknamed the Martians. Torn between the weird and the perfect, Gemma's soul-searchings contain humour and heartache. Dyan Sheldon has also written "The Whale's Song" (winner of the Kate Greenaway Medal), "I Forgot", "Love, Your Bear Pete", "Skywatching", "A Night to Remember", "Ride On, Sister Vincent", "Harry and the Chicken", "Harry the Explorer" and "Harry's Holiday".
