Rebecca, 15, is struggling with something big. Every morning she wakes up and sneezes violently. At school there are further irritations. The science teacher grapples with a class on human reproduction. Impossibly pretty girls in magazines taunt her. Wolves in red cars harass her. Her friends can't find a boy who is truly 'hot'. Rebecca feels allergic to life. She needs to admit a big secret before she can blow those sneezes away.
