Darkness Within: The Keeper of Shadows - Book Three:

After her journey through time, Aria has strengthened her Guardian abilities and
established the Threshold Division-a specialized team dedicated to shadow
management. But as she helps others confront their shadows, disturbing dreams force
her to acknowledge the massive shadow she's been ignoring: the product of her own
childhood trauma.

When ritual sites appear across the city where shadows have been deliberately released,
Aria discovers the existence of the Shadow Liberation Cult-a fanatical group that
believes shadows should be freed rather than contained. Their charismatic leader
preaches that separation from our shadows has stunted humanity's evolution.
As Aria investigates, she's drawn back to her childhood home where a literal and
metaphorical locked door conceals crucial memories. Meanwhile, Detective Michael
Blackwood notices her deteriorating condition and intervenes, deepening their
relationship beyond professional boundaries.

The arrival of Dr. Eleanor Reed-the ex-wife of Samuel, whose shadow nearly destroyed
Aria in the first book-brings warnings about the cult's true intentions: a global ritual to liberate all shadows simultaneously, which would unleash chaos on an unprecedented
scale.

As external threats mount, Aria's personal shadow fully manifests as a separate entity,
forcing her to confront her deepest fears and most painful memories. The final repressed
memory reveals a connection between her family and the cult's origins that changes
everything she understood about her legacy.
In a race against time, Aria must complete the painful process of integrating her own
shadow while stopping the global ritual. The solution lies not in destroying the shadows
or letting them run free, but in finding a balance that has eluded Guardians for
generations.

The Darkness Within is the third book in the compelling Keeper of Shadows series,
blending psychological depth with supernatural suspense. Perfect for fans of Gillian
Flynn, Stephen King, and Joe Hill.
