Hmm… I found a rather unimportant, yet kinda big typo/continuity error in TFiOS.

Under a cut, has quotes, but reveals absolutely nothing of plot, only discussing a minor character name.

So, Augustus’s mother is called both Cindy and Emily. 

“Cindy had to go for a drive.”
— Gus’s dad, referring to her, page 55

“My dad: ‘Emily, this risotto…’”
— Hazel’s dad, speaking to her, page 230

I FOUND THE FAULT IN THE FAULT IN OUR STARS. 

unless I somehow misread this and they are differnet people, in which case please tell me so I can edit this and not be a total goon
