Compelling writing is emotional and engaging with many obstacles. The protagonist is selfless in bravery and there for the benefit of others. An almost impossible urgent mission is another element of an excellent thriller. Dialogue for each character should be unique for their identity, driving their actions consistently. Each character should have purpose and pursue something. Provide interesting relevant details, evidence and subtle differences in the level of importance. Develop the story with clear points readers may have experienced and bring your story to life. Show the audience through clear description with action and conflict, so they can see the purpose and become involved. Connect with the audience in a path through obstacles with focus to an outstanding outcome and change. Readers participate in the decisions and action for what could happen next. Resolve questions or conflicts.

Cormac McCarthy’ The Road, is the profoundly moving story of a journey. It boldly imagines a future in which no hope remains, but in which the father and his son, "each the other's world entire," are sustained by love. Awesome in the totality of its vision, it is an unflinching meditation on the worst and the best that we are capable of: ultimate destructiveness, desperate tenacity, and the tenderness that keeps two people alive in the face of total devastation.
