Jenna has lived a pretty normal life, so far. Well, if you overlook the fact that she is immortal. She knows only a few facts about her early life. 1. She was born in Ancient Greece. 2. She never really knew her parents, because the day after she was born they put her up for adoption. 3. She will have the appearance that she is 16 forever, even though she is over 2,000 years old. 4. She left her adoptive parents' house when she was 13, and has been living on her own ever since. That's all she knows. When her best friend drags her to a place called Camp Half-Blood, claiming that they are both demigods, Jenna goes willingly, thinking that she might get answers about her mysterious life. What if finding out the answers leads to punishment? Is it worth it to know the secrets?
