M . Something woke David from a sound sleep. He saw that Xander was sitting up in bed and thought that his brother had called to him. “What?” he said to Xander’s dark profile. “Shhh.” Bam! David jumped. “Was that a gunshot?” The noise seemed to come from the hallway, but who really knew? Bam! “Xander!” David had felt the noise that time, coming up through the floor into his bed. “Daaaaad!” It was Toria. David and Xander threw back their blankets at the same time and hit the floor running. Bam! Bam! The vibration shot up into David’s feet. Before they reached it, the hallway light turned on. Xander charged through the doorway, with David right behind. “Daaaaad!” Bam! Bam! Bam! Dad was running down the hall toward Toria’s room. He reached it ahead of Xander and swung through. Xander and David stopped at the threshold. Bam! Bam! David not only felt it in his feet, but also in his arm, which was pressed against the door frame. Toria was sitting up in bed, eyes wide.
