The 5th book in the Karin Müller 'Stasi' series -- Stasi Winter -- will be published in the UK by Zaffre on January 9th, 2020.
It sees a return to the Rügen setting of Stasi Child, and also a return for the 'Stasi Child' herself, Irma Behrendt -- now four years older, and a young woman.
But wrap up warm! It's set in East Germany's catastrophe winter of 1978/79 -- with snow drifts as high as houses.
