The Casual Vacancy by J.K. Rowling set a Goodreads record for the all-time biggest “started reading” day, as more than 35,000 people started reading the book in a single day.

 The book unseated Mockingjay by Suzanne Collins as the book with the strongest “started reading” day. Insurgent by Veronica Roth holds third place. As of this writing, The Casual Vacancy has 38 percent five-star ratings on Goodreads.
Goodreads CEO Otis Chandler had this statement: “The Casual Vacancy is one of those stand-out books where people not only pre-order it, they start reading it as soon as they get their hands on it. On Goodreads, it beat the record for our previous all-time ‘started reading’ day which was set by Mockingjay. The pent-up demand is huge and it has been added to-read by 35,600 people,”
