A USA TODAY bestselling series
A California Young Reader Medal–winning series

Sophie and her friends face battles unlike anything they’ve seen before in this thrilling sixth book of the New York Times and USA TODAY bestselling Keeper of the Lost Cities series.

Sophie Foster is struggling. Grieving. Scrambling. But she knows one thing: she will not be defeated.

The Neverseen have had their victories—but the battle is far from over. It’s time to change tactics. Make sacrifices. Reexamine everything. Maybe even time for Sophie to trust her enemies.

All paths lead to Nightfall—an ominous door to an even more ominous place—and Sophie and her friends strike a dangerous bargain to get there. But nothing can prepare them for what they discover. The problems they’re facing stretch deep into their history. And with time running out, and mistakes catching up with them, Sophie and her allies must join forces in ways they never have before.

In this spectacular sixth book in the New York Times and USA TODAY bestselling Keeper of the Lost Cities series, Sophie must uncover the truth about the Lost Cities’ insidious past, before it repeats itself and changes reality.

Customer Reviews

Go Sophitz!

Ok, I believe that Fitz and Sophie should totally be together. First of all, I do agree with the Keefe/Sophie people that Sophie actually really cares about Keefe, but she does not have a crush on him. She has a crush on Fitz, and Keefe INTURUPPTED a Sophie and Fitz kiss moment.

I am so excited for the new book! *squeal!*

Quite possibly the best in the series

Again, every third book is where the action is, and Nightfall is either the best in the series or second to Everblaze.


Okay so there is a serious love triangle going on!! Keefe and Sophie? Or Fitz and Sophie? Dex and Sophie, I just never shipped them. I was worried that were gonna be a couple, if they were it would break Keefe and Fitz hearts. I’m personally leaning a little towards Foster Keefe. But I love the idea of Fitz and Sophie. SOOO DIFFICULT!!!
