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. Re-examine 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.
The cover of Nightfall illustrates (from left to right) Keefe Sencen, Linh Song, and Sophie Foster holding hands to form a circle. They are floating above Atlantis. This is from the scene where the dome above Atlantis has a hole in it, and they're holding back the water to keep the people safe while Psionipaths are on the way.
The three of them are dressed up formally: Sophie is wearing a white, frilly dress with bell sleeves and several petticoats; Linh is wearing a jade green silk coat dress with Chinese button knots sewn on the left side, with black stockings; Keefe is wearing a dark red coat, lined with golden buttons and with pockets on the sides, over a long-sleeved white blouse, and a pair of ankle-length tapered black pants. Sophie and Keefe are both wearing ankle boots.
Sophie is seen to have a slight flush, and she is staring at how far up they are, and how big the drop is ( or maybe how she is holding Keefe's hand). Keefe is staring at Sophie's face and he is smiling. Linh is staring into empty space. Her eyebrows are furrowed in concentration.
It can be noted that Sophie does not have her Enhancer gloves on.
Sophie Foster, Fitz Vacker, and Keefe Sencen talk to Amy Foster, who remembers Sophie. As they make plans to bring Amy to the Lost Cities, Alden, Sandor, and Grizel take charge of matters. Alden uses the same device that Sophie used to sedate her family before leaving the Forbidden Cities to sedate Sophie, Fitz, Keefe, and Amy. Sophie is originally mad at Alden Vacker after waking, but after him explaining her his reasons she accepts what he did was okay. She then has to explain to Amy the entire elvin world, including her friends, Fitzroy Avery Vacker, Keefe Sencen, Dexter Alvin Dizznee, and Biana Vacker.
Following that, she contacts Lady Gisela a lot, sometimes with or without Keefe. She instructs them to do a lot of tasks, which Sophie finds irritating due to her lack of explanations, particularly about Cyrah Endal's death. She eventually tells them, but Sophie is annoyed that Lady Gisela took so long. Her first task is to deliver a note from Lady Gisela to King Dimitar, and get the starstone hairclip that belonged to her. The note explained that she wanted King Dimitar to fight Keefe to see if he was worthy of his daughter being his bodyguard. This causes a lot of conflict between Sandor and Princess Ro (Romhilda is her given name, but she took up Ro).
King Dimitar fights Keefe, and Keefe wins, but suffers serious injuries, which Elwin manages to heal, although Keefe is on bed rest for a week . One might notice that Sophie is feeling very disoriented during this journey, and that is to blame to a kiss that she shared with Dex. This possibly could have ruined their friendship, and Sophie doesn't know what to do. The kiss officially sunk the romantic ship of Sophex.
Sophie and her friends set out to rescue her parents from Nightfall. They discover that there was multiple Nightfalls, and visit both attempting to rescue them. In the the first, they find Alvar unconscious and bring him to Choralmere. At the second, they fight Vespera and find out the original purpose of Nightfall: human experimentation. This means that the humans may have had good reason to start war with the elves, and cutting them out of the treaties was wrong.
After this, Lady Gisela and Ruy Ignis trap Vespera in a Psionipath shield. Lady Gisela then makes Vespera join her, and Ruy rips open a part in the Psionipath shield around Atlantis, causing it to flood. Sophie then enhances Linh's abilities so that she can suck all the water out of Atlantis and keep it out until the Psionipaths arrive so that they can patch the hole with their abilities.
Sophie’s family receives the cure after striking a deal with Fintan, and Amy chooses to keep her memories in the end, partly thanks to Sophie’s enhancer abilities. Bronte is a big help, and Sophie shares a touching moment with her surrogate mother.
At the end of the book, Alvar wakes up, but upon questioning he asks "Who's Alvar?" which ends the book.
