Following their victory against the Shadow Liberation Cult, Aria Montgomery and her
newly-manifested twin sister Alexandra receive an unprecedented invitation: to visit the
Shadow Court, a parallel dimension where shadows have evolved into a sophisticated
civilization with its own laws, culture, and hierarchy.

As the Montgomery twins prepare for their diplomatic mission, the Guardian Council
debates the risks and potential benefits of engagement with this alien realm. Using their
complementary abilities-Aria's light-oriented powers and Alexandra's shadow
dominance-they cross into a dimension that defies conventional physics and
perception.

In the Shadow Court, they meet Lord Tenebris, the enigmatic ruler, and discover a
complex political landscape with factions holding vastly different views on potential
convergence between realms. Their unexpected ally, Luminara-a light-oriented entity
evolved within the shadow dimension-offers crucial guidance as they navigate court
politics.

But when assassination attempts disrupt negotiations and communication with
conventional reality breaks down, the twins uncover a conspiracy: extremist factions
plan to use convergence to dominate both realities, threatening apocalyptic
consequences.

Racing against time, Aria and Alexandra journey to ancient convergence sites where
previous attempts at dimensional merging have occurred. There, they discover a third
option beyond complete convergence or continued separation-permanent thresholds
that would allow controlled interaction while maintaining the integrity of both realities.

In a final confrontation with shadow extremists, the twins must establish a balanced
threshold between dimensions and create a diplomatic framework for ongoing relations.
But as they return to conventional reality, evidence emerges of an ancient threat that
predates both civilizations-setting the stage for the final battle.

The Shadow Court is the fourth book in the innovative Keeper of Shadows series,
blending diplomatic fantasy with parallel dimension exploration. Perfect for fans of N.K.
Jemisin, China Miéville, and Jeff VanderMeer.
