Two of your favourite stars, from two of your favourite shows (Riverdale [1] and Grown-ish [2], to be exact), joining forces in an epic YA-book love story brought to the big screen? Yep, thanks to The Sun Is Also a Star [3], that dream is now a reality.

To celebrate the film bringing the bestselling YA novel to life, we decided to quiz [4] Yara Shahidi [5] and Charles Melton [6] to see just how well they know some of the most beloved young adult books — in which they had to fill in the missing word from iconic quotes . . .

. . . and try to figure out which book a popular quote was from.

Check out the full video above to see their final score, and catch Yara and Charles in The Sun Is Also a Star, in theatres everywhere Friday, May 17!
