The story explores the weight of these decisions, highlighting the strength found in selfless acts and the sacrifices we make for others.

"No Exit" keeps readers guessing by blurring the lines between friend and foe. Each character harbors secrets, making it difficult to discern who is truly innocent. Darby constantly reevaluates her assumptions about her fellow travelers, showcasing how appearances can be deceiving, particularly in desperate situations.
