This book is lyrical and lovely. Grace and Sam are beautiful together, and the mystery of what will happen to Sam hangs over their heads the entire time, lending a sense of urgency to their romance. I felt like there wasn't any plot beyond Sam and Grace spending time together and hoping to find a cure (some outside plot lines would've been welcome). They did have to hide what Sam was from the town so he didnt get hunted, but it didn't play a signficant role. I also would've loved to have Sam and Grace's narrative voices sound a bit more distinct from each other. I sometimes got confused as to which of them was narrating a chapter because they sounded so similar. However, this is a gorgeous book, with a compelling romance, and interesting characters. I recommend it.
