Johanna Trommer was born in 1981 and grew up in Stuttgart, Germany.

 In the course of a one-year stay in the USA in 1998/1999 she took her american High-School Diploma, two years later she graduated in Germany by taking her Abitur (general qualification for university entrance).

Already during her subsequent university education at the Köln International School of Design (Cologne University of Applied Sciences) Johanna Trommer started to work on the first part of the »Grammaton-Saga« (»Letterland – The Fountain of Diamonds«), which is being released in February 2011 by Bastei Lübbe (Baumhaus Verlag). In 2012 the second volume of the fantastic »Grammaton-Saga« will be published; a third instalment is already planned.  

 Today Johanna Trommer is living in her home town Stuttgart, where she is mainly working as an author, but also devoting a good part of her time to her second great passion – classical music.
