The throne rumbled. A wave of gale-force anger slammed into me. "WHO DARES-" The voice stopped abruptly. The anger retreated, which was a good thing, because just those two words had almost blasted my mind to shreds. "Percy." My father's voice was still angry but more controlled. "What exactly are you doing on my throne?" "I'm sorry, Father," I said. "I needed to get your attention." "This was a very dangerous thing to do, even for you. If I hadn't looked before I blasted, you would now be a puddle of seawater."
