I personally LOVE Piper. Granted, I didn't like the fact that she broke up with Jason. Or that she was dating someone new only two months after Jason's death. (Yeah, yeah. I know. She and Jason had broken up but still) She's one of the most powerful demigods ever. She woke up a metal dragon with JUST HER VOICE. She defeated a goddess with JUST HER VOICE. She lulled Gaea, a primidorial deity (sorry I don't know how to spell that.) with JUST HER VOICE. Yes, she's made a few mistakes (stealing the BMW, stealing in general, making people do what she's wanted them to do, etc) but she's always felt remorse for those crimes. Who cried with Hazel when Percy and Annabeth were in Tartarus? Piper. Who was crying tears of joy when Percy and Annabeth came back from Tartarus? Piper. Who stood up for people who couldn't stand up for themselves? Piper. Who has been a good, kind, and loyal friend? Piper McLean. Justice for Piper! She's amazing and doesn't deserve all the hate.
