OK, so this one came from NPR's top books from 2008. I recognized the name Julia Glass from maybe a book of short stories that I read a few years ago for a writing class. I thought the book was very powerful because of it's subject matter- sisters, cancer, suicide, relationships, family, divorce, and on and on.
Based on the synopsis that was given on the back of the book, I was really hoping I'd like the book and give it to my sister to read. But the book isn't about something so simple as sisters who are polar opposites. The book also calls one sister the "responsible one" and one the "impetuous one." I did not find this the case at all! They took turns being responsible and impetuous, but all of this really depends on what the definition of responsible is because both girls are responsible in different ways.
The sisters took turns being the narrator of each chapter. I thought that the two girls were actually pretty shallow characters and even rather obvious and stereotypical opposites. For me, the only reason this book saved itself from the trash pile for me is because of the chapter about suicide and how the remaining sister and her family handled it.
