Berta was born under a rainbow, which as legend has it, should bestow her with special gifts. Instead, she is just very, very tall. Depressed by her height, ignored by the boys, she becomes quiet and introverted. However, at sixteen when she falls in love with a postman against her father's wishes, she discovers that her moods have an extraordinary effect on the weather.
A story of tears, love letters, a deluge, two conflicting villages, a war, a man who falls in love with the left breast of his wife, blood shedding, a priest with very attractive legs, marvellous clouds, a miracle, two coloured rivers, a promise and passion, lots of passion.
