Book 9: Unknown

On May 22nd, 2018, Shannon Messenger announced that there will be a ninth book in the Keeper of the Lost Cities series. It is scheduled to be released in the fall of 2020. The previous book is Legacy, which was released on November 5, 2019. It will most likely include a Short Story as the past three books (Book 6: Nightfall and Book 7: Flashback) and Legacy have.

Title Theories

 * I think that book 9 might be called "Swan Song," since it is likely the last book, and 'Swan Song' is what members of the Black Swan call before they die. ~Yum of the BookHuggerWings
 * I think that book 9 might be called "Unleashed."
 * I think it might be called "Moonlark" like the book series is coming full circle
 * I think book nine might be called "Reborn" because Keefe was sort of reborn in Legacy and Sophie might get a new ability. -Soccerdude121

Cover Theories



 * I believe the cover will have Sophie (of course, duh) Keefe, Linh, and Biana.
 * The cover may show one of Sophie's other power that she could discover
 * The cover may show Keefe with his new ability

Ship Theories


Note: Please only include theories, not opinions or what you personally ship.


 * I think that Biana and Keefe will get together...
 * I think that Sophie might get together with Keefe because he supposedly has an interest in another person.
 * Biana and Keefe. Fitz and Sofie. Marella and dex
 * Dex and Biana, based off of Legacy when they |SPOILER ALERT| hold hands/ Biana gets mad at Stina and tackles her when they are in the mud pit. -soccerdude121

Miscellaneous Theories
 I think that Blur is actually Jensi’s brother because in book 6 on the boat going to Ravagog Sophie said he looked familiar and in 5 Jensi says his brother is a phaser.


 * I think that the Black Swan is dead.
 * Sophie manifests as a Charger-soccerdude121
