Ossi Odyssey [EPUB ebook] 
Olim in Tempus

An East German family is ripped asunder by a border 'incident.’ Raised by proxy families, two siblings are anxious, ambivalent, frightened and resentful of each other. Each enjoys a rich, familial heritage. They are comfortable with their adoptive families. However, as the East German nation begins to crumble, the sisters’ curiosity morphs into an obsession. They are eager to reach out to each other but are terrified by being total strangers. The 'reunification’ of a family proves more problematic than that of a nation.
