When you're 16 years old, it never occurs to you that you might die. Emmi Miller's got a fabulous life. She has tons of friends, does great in school and is an all-star soccer player who played in Europe last summer. It even looks like Sam Hunter, a totally cute baseball player, might be interested in her. And then she gets a virus. No biggy, right? Until the virus goes to her heart and weakens it so much that, without a transplant, Emmi will die. Will Emmi get a heart in time? Is Sam too good to be true? What about her new friend Abe, who has also had a transplant and guides her through these scary times - is he just being supportive or is there more going on between them? And will Emmi realize it before it's too late?
