Percy Jackson and the Olympians, The Heroes of Olympus
How well do you know the Percy Jackson books? Read them all? Good. I don't think there are any big giant spoilers in here, so have fun. Be awesome. No fangirling in the comments, please :P
Wait- I need a second paragraph? Why? Wow this website is really strict on the char act er requirements. If you don't mind I'm just going to keep typing. Says do not use gibberish or repeating characters...
