This book had a great basis, and was written very well but I am not a huge fan of books that focus heavily on flashbacks. If a book is set in the present tense, but there is a lot of scenes set in the past, I find it quiet distracting, and think it takes away from the impact of the main story, particularly one as profound as this. The quirky use of quotations marks [or lack thereof, in the scenes from the past] make sense, after reading t the epilogue,but at the time I found it confusing and a little bit annoying. 
 Overall, I did enjoy the book, but found some of the stylistic choices distracting.
