Keeper of the Lost Cities Books in Order

Keeper of the Lost Cities (2012)⁠^[15-16] introduces twelve-year-old Sophie Foster, whose telepathy leads her from human life into the elvin world. As she joins Foxfire Academy and finds a new home, unexplained knowledge and threats raise questions about her past.

As the opening novel, it establishes the relationships, abilities, and mysteries that the later books build upon.⁠^[1]

Exile (2013)⁠^[17-18] follows Sophie as her bond with a rare alicorn attracts attention while troubling changes affect her abilities. A dangerous assignment and clues connected to the Black Swan draw her further into the mystery of her creation.

This installment develops the mental abilities and damaged-mind storyline that become central to subsequent conflicts.⁠^[2]

Everblaze (2014)⁠^[19-20] places Sophie under pressure to use her abilities while dangerous fires and competing interests threaten the Lost Cities. Her search for answers connects the current conflict with secrets surrounding her adoptive family.

This book turns earlier suspicions into a confrontation that changes her group’s relationship with elvin authority and leads into Neverseen.⁠^[3]

Neverseen (2015)⁠^[21-22] follows Sophie and her friends as they seek refuge with the Black Swan beyond their familiar homes and school. A gnomish plague and encounters with banished elves widen the conflict to other communities.

New allies and disputes between species expand the rebellion storyline and establish the circumstances behind the investigations in Lodestar.⁠^[4]

Lodestar (2016)⁠^[23-24] follows Sophie’s investigation of a mysterious symbol while warnings of an attack threaten the people closest to her. Attempts to understand the Neverseen’s plans unfold alongside preparations for an interspecies Peace Summit.

Its linked investigations bring existing personal and political conflicts together, leaving a crisis that Nightfall takes up.⁠^[5]

Nightfall (2017)⁠^[25-26] sends Sophie and her allies in search of a facility connected to a crisis involving her human family. The investigation draws them into long-concealed experiments and competing plans within the Neverseen.

It reconnects Sophie’s human background with the central struggle while developing the experimentation storyline that extends through later installments.⁠^[6]

Flashback (2018)⁠^[27-28] follows Sophie as the consequences of an earlier arrest bring the Vacker family under scrutiny. A new attack forces her and her friends to reconsider their protection while another crisis exposes hidden connections between species.

This novel turns family history into a wider political problem, changing the circumstances under which Sophie’s group operates.⁠^[7]

Legacy (2019)⁠^[29-30] gives Sophie new leadership responsibilities while her search for her biological parents challenges her place in elvin society. Keefe’s family history and threats involving the dwarven capital reveal another strand of the enemy’s plans.

Its developments in leadership, identity, and altered abilities provide the context for the events of Unlocked.⁠^[8]

Unlocked (2020)⁠^[31-34] combines records about the Lost Cities with a narrative following Sophie and Keefe after the events in Loamnore. Their separate responses to new abilities and the Neverseen conflict move the story beyond the ending of Legacy.

Its narrative bridges the transition into Stellarlune, so the reference material should not lead readers to treat the whole book as optional.⁠^[9]

Stellarlune (2022)⁠^[35-38] follows Sophie’s search for Keefe alongside her investigation of an ancient source of power. Recovered memories and competing factions bring earlier mysteries into the same pursuit.

It advances the main conflict while presenting the events that Unraveled later revisits from Keefe’s perspective.⁠^[10]
