** spoiler alert ** 
 This book was insanely good. I was guessing up until the very end, and had no idea what was going to happen. I really loved the story, and the very big twist that it ended up taking. 
 In this story, Gloria ("Glory") is a seventeen year-old piano prodigy who has just been classified as missing, after escaping from Golden-Hands, a rest center for piano prodigies. So, to figure out what exactly happened to her, we go back 18 months earlier. 
 Francisco Mendoza moved next door from Argetina, and they quickly started a relationship. He learns about how her mother died when she was only ten years old, and how her father only really cares about, at this point, her playing piano. Francisco excels at drawing and painting, and loves wrestling, even owning a jacket. When she goes to Europe to tour, she begins to play the song "Chopsticks" everytime she thinks of him, until it is pretty much all she is playing. After Francisco gets kicked out of his private school, William Dunn, and Glory botches a performance at Carnegie Hall to play "Chopsticks", forcing her father to put her into Golden Hands resting home, so she can have a break, they lose contact. 
 However, all she does whilst she is there, is play "chopsticks". As the last third of the book continues, you realize that Francisco didn't paint or draw anything. Glory did. He didn't have a wrestling jacket. Glory did, and she brought it with her. You realize that William Dunn High School isn't even real, and that it's name (William Dunn) is actually Golden Hands' Chief Administrator and that its "school symbol" is the exact same as the Golden Hands symbol. 
 You start to realize that Francisco is just a product of Glory's imagination, and that he isn't even real. Towards the end of the book, it shows all of "his" paintings with her signiture on the bottom, one of her mother's wine bottles has a picture of a face that is similar to "Francisco's", and Mendoza is a town in Argentina, where the very same wine was made. At the end, it shows a letter written by "Francisco" (in Glory's handwriting) to Glory, about how "he" is leaving, and "he" wishes her to join him, and how "he" loves her. We are lead to believe that she has a mental illness (possibly multiple personality disorder) and that her entire relationship with Francisco was made up. That she ran away to Argentina, because that's where "he" was. 
 I loved seeing the twist in the story. When I picked up this book, I was expecting a sweet book, where the couple ends up together in the end. This is obviously not what I got. I loved the character's, and how it was really up to you what was real, and what was imaginary. After finishing this book, you will be tempted to read it again, just to try and pick up on clues that you might have missed the first time around.
