Like Sophie Foster, Amari discovers a hidden supernatural world while searching for a missing family member and possesses a rare, illegal ability. The story features a high-stakes school setting and a complex bureau of magic that mirrors the Council's structure in the Lost Cities.

This book captures the whimsical yet dangerous atmosphere of a hidden society where the protagonist must prove her worth through magical trials. Fans of KOTLC will appreciate the vibrant world-building, the found family dynamics, and the mystery surrounding the protagonist's unique powers.

A classic entry into the 'hidden world' genre, this story follows a boy who discovers he belongs to a world of myth and legend. It shares the fast-paced action, humorous narrative voice, and the 'chosen one' journey that makes Shannon Messenger's series so addictive.

Focusing on a secret sanctuary for magical creatures, this series involves deep family secrets and a looming ancient evil. It matches the sense of wonder and escalating stakes found in the Lost Cities, along with a heavy emphasis on magical lore.

In a world where creativity is punished, children are sent to a secret magical haven to train their artistic 'powers.' The themes of rebellion against an unfair system and the bond between a group of magical outcasts will resonate strongly with Sophie Foster's fans.

This story features an elemental magic system and a specialized school where students bond with powerful creatures. It mirrors the 'special student' trope and the intense friendship groups that define the Foxfire academy experience.

Blending mythology with a modern setting, this book follows a young girl who accidentally releases a demon and must fix her mistake. It shares the witty dialogue, high-stakes questing, and the discovery of a secret heritage found in Keeper of the Lost Cities.

As the foundational text for many 'hidden world' fans, this book established the school-of-magic and 'outsider-turned-hero' tropes that KOTLC executes so well. The sense of discovery and the formation of a core trio of friends are very similar in tone.

While the characters are dragons, the themes of a grand prophecy, an ensemble cast of friends, and a world divided by political conflict are very similar to Sophie’s journey. It features the same blend of lighthearted friendship and high-stakes war.

This series explores a magical school where the lines between hero and villain are blurred. Fans who enjoy the complex social hierarchies of the Elvin world and the 'identity crisis' themes Sophie faces will find this equally compelling.
