I find it really hard to pick a favourite book..I think like rubylynns said, I read them together so quickly (I think it was 3 days) that they just merged into one epic book that had me hanging on every word
If I look at the events that happened in each book I think maybe I like Catching Fire the most. I found Mockingjay really traumatic, but still loved it, and it definitely contains some of my most loved quotes.
Here's my Hunger Games pinterest...which I plan to grow more this weekend http://pinterest.com/kitty_tales/hungry-for-the-hunger-games/
So have many people here read the books more than once? I'm about to start my second read through and I'm really interested to see how different they are now I know how everything turns out
