The Fault in Our Stars by John Green

Hazel has thyroid cancer that has affected her lungs. Augustus looks like a hunky picture of health, despite having lost a leg to bone cancer. The two teens meet at a cancer support group and fall in love. And though they know there's no long-term future in store for them, they make the most out of every moment they have together. While you'd expect this to be a depressing book, it's anything but. Yes it's sad. But it's also funny, sweet and heartwarming. The book's title comes from William Shakespeare's Julius Caesar: Men at some time are masters of their fates: The fault, dear Brutus, is not in our stars, But in ourselves, that we are underlings.
