the plummet to the bottom was a nightmare , and maddie could do nothing but scream into sam 's chest , his arm wrapped around her head , his body taking the damage during the punishing dive to the bottom of the steps as they fell at a frightening pace , rolling over and over until finally , their bodies stopped , sam 's back hitting the wall at the bottom with a force brutal enough to bring them to a halt before he rolled forward , sprawled on top of her .
