Throughout the month of August, Jade from @Jadeyraereads on Youtube is hosting a readathon called Polarathon.
This is not the first time she's hosted this readathon but it is the biggest one so far. The readathon is based around the polar fantasy genre, but you don't necessarily have to have read polar fantasy, just taking part is the fun of it!
This year Jade has set up a JustGiving page to raise money for a polar bear charity and to spread awareness about climate change.
Jade has pledged that for every 100 pages she reads she will donate £1! A lot of people are doing the same in order to reach the target.
This is such a fun readathon to take part in and it also spreads awareness which is wonderful.
