21st Century Literature discussion

This thread is for discussing Part One of this month's moderator pick, Do Not Say We Have Nothing by Madeleine Thien. Spoilers allowed but only for part one, please!

I am still working my way through but will add a summary of part one later for anyone who can't remember what happens in this part.

More questions to come, but for now - what do you think of this book so far? What do you think about the switches in time and stories within stories?

Thanks Caroline. I need to dig out my copy to avoid potential spoilers because I am struggling to remember what came where.
