100 Days of Sunlight, by Abbie Emmons

When an auto accident causes Tessa to lose her sight, the promise that the loss is probably temporary is small comfort.  She holes herself up in her room and cuts herself off from her friends.  Her grandparents decide to take things into their own hands and place an ad for a person to come help Tessa do things like dictation.  Tessa is enraged that they would do such a thing and when Weston shows up for the job, she takes her frustration out on him.  He isn't bothered, he's seen worse.

Weston is a double amputee -- the result of an untreated infection from an accident three years prior.  Through flashbacks, he describes the process he went through to come back, working through not only his disability but also his anger at his fate -- knowledge that he applies to Tessa's situation.  However, he has an advantage:  she doesn't know he's an amputee.

Over the next hundred days, through patience and stubborn persistence, Weston works through Tessa's barriers and gradually helps her deal with her blindness.  However, he knows that one day soon she'll get her sight back and then she'll see him as he truly is.  And he fears what she will do.

A terribly sweet and utterly gratuitous romance.  Weston is pretty much the Perfect Boy -- kind, considerate, generous, with just a small amount of naughtiness (he gets into fist fights).  He adores Tessa.  And of course, he has nothing better to do than dote on her for three months.  Needless to say, we know that his silly fears about her hating him when she sees his disability are nothing big, so we're flipping the pages waiting for that swoon-worthy happily-ever-after kiss.  And this is the kind of story that delivers just what the readers want.  In sum, pure unadulterated literary junk food.  Grab a pint of Ben & Jerry's or a package of Oreos and dig in!
