My gosh. This book was recommended to me by a friend and I wasn't sure what to expect when I started reading it. Honestly, the blurb doesn't do it justice at all, in my opinion. I thought it would be a little cliche - sick girl sees boy from her window, they fall in love without having ever even met, etc.... Now, though, I'm so glad I gave it a try! 
 Madeline's character is believable and throughout the entire book, I just felt for her. I understand the close bond she has with her mother and her nurse, Carla, but also her desire to get out into the world and experience more than that. Of course love (sprung from watching each other through windows and IM'ing) is what brings out this desire in her, but that didn't feel cliche or annoying to me. Some moments in this book had me hold my breath and others made me want to chew my nails with anxiety... and then, of course, there's the plot twist. 
 I won't discuss this plot twist in detail, but... wow. At the beginning, I was a little afraid that it would become cheesy and cliche after all; but then I kept reading and I was completely sucked in by the story. I don't even know what I was feeling, but there were a lot of feels all at once. Wow. Just... wow. I did not see that coming, but it was, in my opinion, pretty brilliant. 
 I'm not a big fan of the ending, because after everything, everything (I am so sorry, but I couldn't resist that bad pun), it just felt too rushed and too open to me. I would have liked to read more about what happened to everyone and how things ended - not just for Madeline and Olly, but also for her mum and Carla, for example. Despite that fact, though, I thought this was a very good book. I couldn't put it away.
