The Most Popular Quote From The Fault In Our Stars

Fate had plans in store for Hazel Grace after she was forced to attend a cancer support group. There, she met the charming and witty Augustus, who was seemingly and magnetically pulled toward her. Both book lovers, they agree to read each other's favorite novels, which becomes the premise of the entire plot when Augustus utilizes his previously unused "make a wish" to get Hazel to Amsterdam to meet her favorite author (via IMDb). On the plane ride there, Augustus reads her favorite book, "An Imperial Affliction," and she watches him.

This scene prompted one of the most memorable and most quoted lines in the book, according to Insider: "As he read, I fell in love the way you fall asleep: slowly, and then all at once."

This line let everyone know that although she had slowly been falling in love with Augustus, at that very moment, she knew she was his. One search of #SlowlyThenAllAtOnce on Instagram reveals dozens of posts, with the famous quote even printed on shirts and bracelets. Collecting over 46,000 likes on Goodreads and printed over several aesthetically pleasing graphics online, it's safe to say the quote is definitely a fan favorite.
