Sunburn- phoebus apollo

-- xix. percy fights a god

"PERCY," Annabeth said. "How-?"

"I-I don't know. I don't understand."

"You heroes are always the same," Hades said. "Your pride makes you foolish, thinking you could bring such a weapon before me. I did not ask for Zeus's master bolt, but since it is here, you will yield it to me. I am sure it will make an excellent bargaining tool. And now... my helmet. Where is it?"

Percy looked like he wanted the world to swallow him whole. 

"Lord Hades, wait," he said. "This is all a mistake."

"A mistake?" Hades roared.

The skeletons aimed their weapons. From high above, there was a fluttering of leathery wings, and the three Furies swooped down to perch on the back of their master's throne. The one with Mrs. Dodd's face grinned at Rhea eagerly and flicked her whip.

"There is no mistake," Hades said. "I know why you have come-- I know the real reason you brought the bolt. You came to bargain for her."

Hades loosed a ball of gold fire from his palm. It exploded on the steps in front of Rhea, and there was her mother, frozen in a shower of gold, just as she was at the moment when the Minotaur began to squeeze her to death. 

Rhea couldn't speak. Apollo hadn't lied to her. She reached out to touch her, but the light was as hot as a bonfire. 

"Yes," Hades said with satisfaction. "I took her. I knew, Rhea and Percy Jackson, that you two would come to bargain with me eventually. Return my helmet, and perhaps I will let her go. She is not dead, you know. Not yet. But if you displease me, that will change."

Percy hesitated.

"All, the pearls," Hades said. "Yes, my brother and his little tricks. Bring them fourth, Percy Jackson."

Percy brought the pearls out of his pocket.

"Only four," Hades said. "What a shame. You do realize each only protests a single person. Try to take your mother, then, little godling. And which of your friends will you leave behind to spend eternity with me? Go on. Choose. Or give me the backpack and accept my terms."

Percy looked at his friends. 

"We were tricked," he told them. "Set up."

"Yes, but why?" Annabeth asked. "And the voice in the pit--"

"I don't know yet," Percy said. "But I intend to ask."

"Decide, boy!" Hades yelled.

"Percy." Grover put his hand on Percy's shoulder. You can't give him the bolt."

"I know that."

"Leave me here," he said. "Use the fourth pearl on your mom."

"No!"

"I'm a satyr," Grover said. "We don't have souls like humans do. He can torture me until I die, but he won't get me forever. I'll just reincarnate as a flower or something. It's the best way."

"You three go on," Annabeth insisted, drawing her bronze knife. "Grover, you have to protect Percy and Rhea. You have to get your searcher's license and start your quest for Pan. Get their mom out of here. I'll cover you. I plan to go down fighting."

"No, Annabeth!" Rhea protested.

"No way," Grover said. "I'm staying behind."

"Think again, goat boy," Annabeth said.

"I could stay behind," Rhea said, her lips trembling. "With Apollo's blessing and all--"

"Lord Apollo won't be much help with the underworld being so far out of his domain, Rhea." Annabeth snapped. "Besides, look what happened to you once you stepped foot in here-"
