The book is beautifully written and the narrators did an excellent job. I did not like few things but I will talk about those later. The concept is original. I picked up this book by reading "inspired by a true story." Now I am curious to know how much of the story was actually true and which parts were fictitious. The book is thought provoking. I think this book would appeal more to others but I still liked it. Lastly, I don't know why, but the whole concept of a "blue bottle" inside everyone intrigued me.
Bad points: I felt the characters were not fully developed especially the grandmother, the father, and the aunt. I think the author should have written more about them to give the full picture. There were few events in the novel that I felt were unnecessary, and the story would have been better without them. I won't elaborate more on that. I was highly disappointed with the whole mystery. The author built it up by mentioning minor details here and there.
I give this book 8.5 out of 10.
