After Ever After by Jordan Sonnenblick

"They scheduled my transplant, jeff. If my cancer is in remission, they're going to do it three weeks after the statewides. Then I'm going to be in isolation for at least three weeks."
          I stopped pedaling. I can barely do math when I'm sitting still. "Wait, but that means--"
            "I'm not going to be at graduation."
    This couldn't be. It just couldn't be. "Tad," I said, " get on the treadmill. Please."
    "Jeff, weren't you listening just now? There's no point. I'm going to be in a damn hospital bed on the day you...."
     "I don't care! Get on the treadmill! You can't just quit on me!"
    "I'm not quitting on you, I swear. It just.... I'm pretty dizzy lately. And it hurts to walk."
     " GET ON THE TREADMILL!" I shouted. "Get on ! Get ON!" I started trying to push Tad's wheelchair across the room, but he locked the wheels. " You have to! You have to!" 

It is one of my favourite books, lovely story of two teen friends and also two friends who are fighting with cancer. How hard it is for them being different in the school, where everyone tries to fit in. Anyone who is different is made fun of. Their individual ways of dealing with it. Their bonding ... their vulnerability.. their secrets.. their family.. . Just everything about this book was almost perfect. Loved it.
