'It's the night of the Po-town Spill, and things are getting weird. Strange lights fill the sky, the house across the street is melting, and the neighbors are turning into meat puppets. Lexa's big sister and parents are gone, and all she has for company in this calamity is her rag doll, Vespertine. Luckily, since the Spill began Vespertine can talk, and has plenty to say.'
