In this book, Rubina accomplished the impossible – she combined three different genres: a gothic novel about dolls and puppeteers, a family detective story, and a psychological drama. Little Petya stole a girl with red-gold curls from a stroller. The child had to be returned to the nanny, but Petya had already made up his mind. This girl would be his main doll. Petya and Liza will be bound first by a long friendship, and then by an unbearable love. They will have to survive the death of their son, born with Petrushka syndrome.
