Let us know if you have any news reguarding Shai!
"She auditioned for The Fault in Our Stars not because she needs the part (I mean, she’s in the new Spider Man movie, for God’s sakes) but because she loves the book. Her depth of understanding were immediately obvious in the audition and for me there could be no one else to play Hazel. (There were a bunch of really good auditions, but Shailene just understood Hazel as I imagined her.)” - John Green via his Tumblr
