Piper McLean : The Lost Hero

Piper is a gorgeous girl of Cherokee decent. At first, she has chocolate brown hair that is cut choppy and uneven, and got teased because of this by Drew. Her eyes change color like a kaleidoscope going from brown, to blue and green. She wears faded jeans, a snowboarding jacket and hiking boots. She often uses her beauty and charismatic voice to distract enemies. Her skin color is mixed with Native American and white.

I think it's fairly obvious who her Greek god parent is. I will admit I was a bit surprise when it happened in the book. Didn't see it coming And of course her claiming is different from the other god parent's claiming their kids.. because her God parent... makes a bit of a spectacle of it apparently..
