I ended up reading 19 hours which was way more than I thought I would be able to when I signed up. I listened to 8 hours 24 minutes of audiobook and read 945 pages. I finished six books: The Walls Around Us, Unbreakable, The Mystery of 99 Steps, Champion, The Clue in the Crossword Ciper and Open Road Summer.
I had fun participating in this Readathon and will definitely do the next one. You can see photos I posted during the Readathon on my Instagram account.
