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.

Unfortunately, battle training can’t help a beloved friend who’s facing a whole different danger—where the only solution involves one of the biggest risks Sophie and her friends have ever taken. And the distraction might be exactly what the villains have been waiting for.

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
 * 2) The book will NOT be one long flashback.

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. Sophie 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 or the Crooked Forest.

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 might have human jeans on.
