The Fault in Our Stars is the fourth solo novel by author John Green, published in January 2012. The story is narrated by a sixteen-year-old cancer patient named Hazel, who is forced by her parents to attend a support group, where she subsequently meets and falls in love with the seventeen-year-old Augustus Waters, an ex-basketball player andamputee.
On his Tumblr blog and his YouTube vlog, Green stated that "the title is inspired by a famous line from Shakespeare's play Julius Caesar (Act 1, scene 2). The nobleman Cassius says to Brutus, 'The fault, dear Brutus, is not in our stars, / But in ourselves, that we are underlings.'"
