In 2016 Kathrina published her first volume of poems, called “Mein schwarzes Herz”. It is written in German and includes over 90 poems and is illustrated by works of Cuculum and Severin Frank.
The poems published in this book were written by Kathrina at the age of 14 to 16 years. Even though they were published some years later, she decided to not rework the content and linguistic of the texts. Thus the printed version effectively presents the original version of the poems.
