AMAZING! They are so so fun and make reading a book an even better experience. They give you a chance to fangirl and really rave about a book with someone.
I've also found that it's easier to push through boring books if you know there's a friend reading it with you. Also, buddy reads give you an insight into how others interpret books or chapters differently from you.
Overall, I really enjoy buddy reads and would highly recommend doing them. If you don't know anyone willing to do a buddy read then you can always contact me on
Twitter` and i'd be happy to read anything along with you!
