Gift set: book She is not my sister + 3 postcards

The book «She is not my sister», two postcards featuring the main characters of the story, Alice and Lola, and a postcard with the signatures of the authors — Asya Lavrinovich and Alex Hill.

We are only moving towards one... thing — happiness. The main thing is not to stray from the path and not to be afraid of change.

They are completely from different worlds. Alice Romanova lives in a modest apartment with a wonderful and loving mother. Lola Spivak — in a luxurious country house with a strict but caring father.
And then, on Valentine's Day, they unexpectedly find out that their parents are getting married. Now the girls will have to live together, and they haven't even communicated once!
Lola and Alice decide to agree: they will not interfere in each other's affairs and will not flaunt their proximity at school. It's pretty simple. But when problems start to arise one after another, they can't do without help.
Will they be able to find a common language? And possibly even become... sisters?
