Louisa Clark has gotten a new job as the caretaker of Will Traynor, who is now confined to a wheelchair. Will hates his new life and Louisa doesn't care much for him - he's grumpy and acerbic.
Soon, however, Louisa and Will begin a friendship that has the unique intimacy due to his situation and her job. Will starts pushing Louisa to break out of her shell and try new things - adventures that he can no longer have.
This unlikely pair have a tremendous influence on one another. It's a heartbreaking yet heartwarming story and, for some reason, it really struck a chord with me. If you ever evaluate your own life or think "what if," then this story will impact you, as well.
