The Codex of Forgotten Souls oleh Jamie Ellisons

Veritas, a city of gleaming towers and whispered secrets, hides a truth buried beneath layers of manufactured reality.  Seventeen-year-old Milo Harper, a mage apprentice, feels the dissonance, the echo of a raw, untamed magic pulsing beneath the city's glittering facade.  He yearns for a connection to this forgotten power, a resonance with Veritas’s hidden heart.  The discovery of a hidden alley, a doorway etched with ancient glyphs, leads him to the Library of Lost Memories, a realm beyond time and space where forgotten histories whisper within shimmering crystal orbs and ancient scrolls.  At the library’s heart lies the Codex of Forgotten Souls, a tome of immense power that both terrifies and enthralls.

Touching a single orb unleashes a torrent of forgotten magic, transforming Milo into something more, something other.  He is becoming the key to unlocking Veritas’s suppressed past, a power the Obsidian Veil, a clandestine organization dedicated to maintaining the city's fabricated peace, will stop at nothing to control. Ruth Wilson, an agent whose obsidian eyes reflect a lifetime of buried secrets, hunts Milo with ruthless efficiency, her loyalty to the Veil fueled by a personal tragedy she believes the forgotten magic caused.

Within the library's ethereal labyrinth, Milo finds an unlikely mentor in Claire Riley, the enigmatic keeper whose past is as intricately woven into the library as the threads of a forgotten tapestry.  On the city streets, Kaitlin Lawrence, a rebellious street artist, uses vibrant murals to subtly awaken the city’s slumbering consciousness, her art a silent rebellion against the Veil's manipulations. Daniel Bryant, a historian haunted by a fragmented family memory, desperately searches for answers in Veritas’s obscured past, his quest leading him to Milo and the growing resistance.

Each memory Milo unlocks binds them together, revealing not only the city’s secrets but their own hidden connections to its forgotten heart. They uncover a conspiracy that reaches back centuries, to a vanished civilization and imprisoned gods whose influence still subtly shapes the city's fate.  But accessing the past comes at a cost. Each touch fragments Milo’s own identity, blurring the lines between who he is and who he was.  He must choose: embrace the power and risk shattering his own soul, or surrender to the Veil and condemn Veritas to an eternity of manufactured reality.  The fate of Veritas, and perhaps reality itself, rests on his fractured shoulders.
