Synopsis
Sophie Elizabeth Foster doesn’t know what or who to believe. And in a game with this many players, the worst mistake can be focusing on the wrong threat.

But when the Neverseen prove that Sophie’s far more vulnerable than she ever imagined, she realizes it’s time to change the rules. Her powerful abilities can only protect her so far. To face down her ruthless enemies, she must learn to fight.

In this unforgettable seventh book in the New York Times and USA TODAY bestselling Keeper of the Lost Cities series, Sophie must let the past and present blur together, because the deadliest secrets are always the ones that get erased.

Shannon Messenger has also said:
 * 1) Memory plays a big role in this book.

Cover
The cover was revealed on March 8th, 2018 at 12:00 ( Pacific Time ).

Sophie is seen aiming the goblin throwing star at an unknown someone or something and appears to be left-handed. She seems to be standing on the mossy ground and a staircase is visible in the background. Sophie is wearing a purple tunic with green tights, knee-high boots, and a cape with a different crest than her Ruewen crest. The crest could be a butterfly or a pair of wings. It can be noted that her tights have been scratched by some sort of claw or ripped on her right thigh on our left, or she has zippers. Tam and Wylie are seen using their abilities in the background, trying to create something together that appears to be a portal where the staircase is. Sophie seems to be in a forest of some kind as there are trees framing the background. It can be noted that the staircase in the background could be Alluveterre, the Crooked Forest, or the Wanderling Woods.

It can also be noted that Sophie has her Enhancer gloves on and is wearing two Nexuses, one on each hand. This could be one of Dex's gadgets disguised as nexuses.

Tam does, in fact, have human jeans on.

Sophie, Tam, and Wylie are wearing identical capes: black with gold trim and underside.

Quotes/Teasers

 * "So is it strange coming here and not being the one on trial?" Keefe asked, checking his expertly styled blond hair in a shiny facet on one of the jeweled walls before he followed Sophie into Tribunal Hall. "Because I'd be happy to help you break a few laws if you're feeling left out."
 * "I'm tired of being weak," Sophie whispered. "I want to fight back—and I mean really fight."
 * Keefe smirked. “Epic Fitzphie fail.”
 * I’ve had to keep secrets my whole life, Sophie reminded him. It’s a hard habit to break. (Telepathic conversation.)
 * “Looks like things are about to get interesting here in sparkle town.”
 * “With the Neverseen...we’re always missing something. There’s always some trick we don’t see until it’s too late.”
 * “Embrace the sparkles, Foster,” Keefe told her. “They look good on you.”
