Michelle from The True Book Addict is hosting her second Sit Down and Write write-a-thon at her Stories Inside blog! I'm not participating in NaNoWriMo, but am going to use this as motivation to catch up on my backlog of reviews.
While I'm usually a massive failure at read-a-thons, I love the idea of a write-a-thon! I participated in something similar awhile back and it really helped me catch up on reviews.
It runs from November 12 - November 25.
You can find out more details and sign up here.
Wish me luck!
