Ekaterina has illustrated "National Trust: When Winter Comes," the final book in a seasonal series for ages 2-5 published by Nosy Crow in partnership with the National Trust. Her illustrations capture the magic of winter – from ducks skating on frozen lakes to building snowmen, feeding birds with Mum, and clearing snowy paths with Dad, before ending with cozy moments of hot chocolate and gingerbread. Released on October 14, 2025, Ekaterina's artwork brings warmth to winter scenes, celebrating a young child's joyful discovery of nature and showing readers all the wonder to be found in the coldest months of the year.
