Suspense is the element that authors use to try to leave the reader hanging, trying to figure out what will happen next, especially when the author does this at the end of the book without actually telling what happens. This leaves a particularly strong effect. Suspense is what gives the reader the on-edge feeling. Suspense builds in order to make those final moments, no matter how short, the most memorable moments in the work. For example, in The Road by Cormac McCarthy suspense builds constantly.
