This book is definitely not my style. I found it difficult to follow for the first 80% and I guess this is supposed to reflect the state of mind of the MC. I can imagine this book could be used in English Lit classes where the readers discuss the motives and mindset of the characters so if this is the kind of reading you like, then you'd probably love this book.
The MC lost her child but we don't know the details until the 80% mark. She's struggling to cope (understandably) and one day, starts driving and doesn't stop until the car breaks down. Then she walks, hitches and takes a bus, ending up in Mexico. This is where she starts to process her grief but it's still quite abstract. One of her new friends asked her what happened and that's where we get the full story.
I will admit to teary eyes at this point because we get to see her raw grief. The arrival of her mother is where the MC starts to show some real growth and the book ends with her moving towards a better future.
