Perhaps I should add a "tear-jerker" shelf to organize books such as this. 
 A woman is hired to be a companion to a man who was paralyzed in an accident. Facing a life so different from the high-powered and active one he had before -- and one so out of his control -- Will wants to die. Louise can't face that idea and does her best to give him something to live for. In the course of their knowing each other, Will brings Louise back to life, awakens her from her going-through-the-motions life. 
 (view spoiler)[Moyes did a great job of offering hope, though couching it in Louise's despair, that you're not absolutely certain what choice Will is going to make. I was pretty sure by halfway through he wasn't going to change his mind, which is what makes Louise's efforts so sad. However, Will is so contrary I thought perhaps he'd choose to live once he forced his loved ones to realize they weren't in control of him. (hide spoiler)] 
 I think it's telling that we never get Will's point of view (view spoiler)[ except for a letter to Louise after his death (hide spoiler)]. The story is told mostly by Louise, first-person, but interspersed are comments from those around Louise and Will. Thematically it works because part of Will's argument for suicide is that everyone else seems to have more of a say in his life than he does. 
 It's a tough concept. I couldn't help but feel angry that Will was willing to throw away what life he had, as though it wasn't worth anything any more. I don't know what it's like to live like that, but I've seen people fight for their lives and it feels like an affront. It feels like giving up, though I'm sure some folks would say it's taking control. I've also seen people say "enough" and give up the fight, particularly with cancer, and take what's left. So how is this any different? I don't know.
