Hm, I heard a lot of good things about this, but in the end it was only an okay book for me. Not for any technical faults, but because I was probably the wrong audience for it. For one thing, there are a LOT of musical references-- classical/rock/punk/etc musicians and styles are name-dropped everywhere, and since I am not wise in the ways and classifications of music, all those references were mostly lost on me. As a result, I became distanced from some really integral parts of the story...and thus viewed the whole drawn-out coma in a rather academic light rather than an emotional one. 
 So while the main character, Mia, was pondering her past and present, half of my brain was commenting on how the storyline is formatted like a character-driven, plotless, adult literary novel rather than the plot-driven (but still strongly character-based) YA/sci-fi/fantasy/action-thriller novels that I usually gravitate towards. The premise of the novel, answering the question "do I stay? do I go?", takes the full length of the novel to complete because every single step of the way you are interrupted with another flashback/memory of Mia's life story. It's slow...and since I didn't care much for the music, and didn't particularly find her family all that interesting, I started to skim pages very fast. 
 So to sum it up, if you've got time, patience and have a good memory for music, then this is a good, emotional book. Anyone who is a bit more impatient, stay away.
