The Fault in Our Stars, written by John Green, is the story of love, heartbreak, illness, loss, and death. It tells the tale of two teenagers, Hazel Grace Lancaster and Augustus Waters, who have both been diagnosed with cancer. The two bond over a book called An Imperial Affliction and its open ending. Shortly thereafter, Hazel and Augustus are boarding a plane to visit the book's author in hopes to get an answer to the question, "What happens after the story ends?" - a question that shows up often throughout the plot in their personal lives as well.
