India lives in a large, luxurious house with a mum she can't stand and a dad she adores, though he hasn't had much time for her recently. She seeks solace in her journal, which she keeps in sincere imitation of her heroine, Anne Frank. Treasure lives on the local council estate with her loving and capable grandmother. She is devoted to her nan but lives in fear of having to go back to live with her mother and violent stepfather. A chance meeting sparks a great friendship between the girls. And when Treasure has to run away to avoid her stepfather, India comes up with a hiding place inspired by her favourite writer. India hasn't got a real secret annexe like Anne Frank - but she has got a hidden attic . . .
