while it doesn't seem like its sad now there is a very large possibility that its going to be sad somehow, all authors are kinds evil in that sense. But this book doesn't revolve around the idea of cancer and death and horrible lives. it shows you that cancer doesn't end your life, but opens up the idea of do something, a motivations to do something or be someone just before your time is up. it highlights the friendships and all the good Tims alongside the bad times, and for people with cancer, or people who are those with cancer, we need reminders that while it sucks, its not all bad, and that is very important.
