Rosalind is having the worst holiday of her life - her mother is away at school, so she and her brother have to hang around visiting dad and his new wife! Of course, this is not a problem: Rose has plenty of books with her, and she would somehow survive two weeks, when suddenly Shlyopa, her half-sister, appears, and the life of Robbie and Rose turns into a real nightmare. It is absolutely impossible to cope with an emotional, sharp, athletic and strong sister. But one day the children find something unusual in the forest... To keep the discovery a secret, like it or not, you will have to become a team, but will you succeed?

A free continuation of the fairy-tale cycle “Psammead” by the English writer Edith Nesbit. Translation: Elena Mikerina.
