I'm not sure that this book deserved all the hype. It is good, yes but it was only 3.5 stars for me. There isn't anything that stands out about this book that would lead me to giving it even 4 whole stars. I was waiting for some big reveal toward the end and that never happened. 
I often got lost with the many different characters in the two timelines and took me a minute to get back on track. 

The narration was done well enough but the voice given to TJ often made me think that she was a boy and I had to keep reminding myself that this was not true.
