“Kate Who Wanted to Become a Grandfather” is the first book in the series about the enthusiastic and determined Kate and her grandfather. Little Kate is quick to act and make her spontaneous ideas come alive. Grandfather, though, knows how to live calmly and quietly, and keep his life the way he likes it. Kate also wants to try living in her grandfather’s world and finds fun, humorous ways to be like him—at least on the outside.

In March 2026, the play Kati will Großvater werden premiered at Deutsches Theater Göttingen, based on the book by Signe Viška and Elīna Brasliņa, directed by Lisa van Buren, with dramatization by Sonja Bachmann.
