So the Olympic Games Readathon is hosted by Ishi Times. I've leaven the link to her announcement video so that you can look up the information for the readathon yourself, but basically you are competing in a challenge at Camp Half-Blood, and each cabin has their own challenges to read.
I'm part of Poseidon's team. So here are the challenges I must complete:
Read a Book set at Sea or on the Coast:
Read a Book where the Main Character uses a Sword:
Read a Book with a Non-Human Main Character:
Finish a Book in 3 Days:
Read a Book You Haven't Heard Much About:
Advanced Challenges which I don't have to complete but am aiming to do:
Read a Book Published in Last 5 Years:
Read a Book with Blue Cover:
Read a Book featuring Magical Creatures:
