It's the story of the author's grandparents' lives during the 1910's: how they met, got married, and had children, but also about their social milieu, political discussions, union organizing, personal and political struggles when food was scarce in 1918-1919, etc.
ooh, I'm sorry this isn't (I assume) around in English! That sounds absolutely fascinating, down to the various small details you describe. (And the pronoun stuff! Would be glad to hear more about that if you feel like writing it up at some point.)
