Query: How little we know about anyone

Main characters in this book are a single mother with a young son and her relationship with her mother. The daughter fears that her mother is going senile but the mother begins to write the story of her life and hands chapters to the daughter to read. The unfolding plot is very suspenseful when the mother turns out to be someone that has a huge secret to tell. A bit of historical fiction, relationship twists, and drama.
