The Shadowless Veil. The Shadow Realms Trilogy, #1

An Unbound rogue. A imprisoned king. A realm waking up to war. Vespera is an anomaly - a woman without a shadow, a void through which magic passes without purchase. For years, her unique nature kept her invisible to the dark court and the lethal magic ruling the realm. But when an energy surge fractures the ancient siphon chamber, she is thrust directly into the heart of a nine-century-old power struggle.
Caelum was born to rule, but centuries as a prisoner left him bound by blood and magic. To save his people, he needs Vespera's Unbound abilities to systematically dismantle the magical nodes holding the border seals intact. As they navigate deadly court intrigue, lingering shadows, and broken anchors, every step forward strains the fragile balance between stability and utter ruin. When the final anchor shatters, releasing the full force of compressed history, Vespera and Caelum must decide where their loyalties lie.
The war for the shadow realms is beginning and together, they must stand against the rising storm. The Shadowless Veil is the atmospheric first book in a high-fantasy romantic thriller trilogy, perfect for fans of intricate world-building, Unbound magic systems, and dark court intrigue.
