Have you got any subtitle for the book and what's the author name?

Hello, the authors name is "Lutz von Peter". There is no subtitle, however the German published version has the word "Thriller" on the front.

Note to all:
the title is "The Ostland Protocol".
There is a reference in the description to "Fatherland" by Robert Harris, but this cover competition is not for Fatherland, but for "The Ostland Protocol"
