My Special Book that I Read

I have just finished reading  The Mark of Athena, by Rick Riordan, which is an exciting book with quests, battles, and Greek and Roman mythology. It all starts when Leo gets possessed and fires on the Roman base camp,which triggers war and the Greeks flee. They head to Ancient Rome, where they need to save a friend that is taken hostage. Meanwhile, Annabeth has a quest of her own: to face her worst enemy in order to fix the problem between the Greeks and the Romans. The end of the story ends in a deadly cliffhanger, but of course, I will not spoil! 

Here is the song I picked for when Annabeth is on her own.
