Absolutely beautiful, painful book.
The description of the book gives most of the content warnings. Don’t pick it up unless you’re prepared to be absolutely wrecked. I could only read it in slow doses.
The book begins with Deraniyagala describing fleeing from the wave, the last moments with her family, and the shock and trauma as she tries to continue to live after the disaster.

Her writing is incredibly powerful. I cried a lot through the book.
I also found myself smiling and laughing some towards the end with her descriptions of her college years with her husband. I don’t know that I’d reread this, but I’m glad I read it.
