The title comes from Shakespeare's Julius Caesar when Cassius says to Brutus: "The fault, dear Brutus, is not in our stars, / But in ourselves, that we are underlings."
This is a fictional, young adult book and I LOVED it. It was beautiful, sad, funny, and super readable. It's one of my favorites of the year so far.
