Daughter of Apollo (Percy Jackson)

Spencer Smith looks like an ordinary girl on the outside, and for a while, she thought she was normal. She was 16, went to a normal school, and had a normal-ish friend. But one day, everything changed when she realizes there's a whole other world and it was meant for her. Spencer goes to Camp Half Blood, the safe haven for demi-gods like her. Everything is perfectly fine for a while, but then Chiron, the beloved camp director, sends her up to the attic to meet Rachel, the new speaker for the spirit of Delphi, who tells her prophecy to save her father, Apollo on a grueling quest that makes her question her friends, family, and the strangers walking down the street.
