What if Attack on Titan fell down the rabbit hole?

Imagine Attack on Titan reimagined through the lens of Alice in Wonderland, but with a dark romance so charged, it threatens to eclipse the chaos around it.Equal parts cerebral, savage, and seductive, it twists through mystery and madness, putting epic action and dark romance at the heart of everything.



Synopsis

Gaia Draven is imprisoned in a world forbidden to mortals with no memories of who she is, how she got there, or why an ancient horror masquerading as a man has decided to keep her alive.Sorin is the prison's most ruthless, powerful, and enigmatic resident. He follows his own code of ethics and doesn't bother to hide the monster leashed behind his smile. He offers Gaia an alliance: he will keep her alive and help her uncover what she’s lost, but in return, she must join his cause and help him settle an old debt.Her past returns in pieces, and what begins as a search for answers quickly escalates into something far more perilous. Each memory draws her closer to a figure from the ruins of her old life, revealing a loyalty to another immortal’s ambitions that ignited a vicious, bitter feud.Now, as Sorin and Gaia form an unlikely partnership, she must rediscover the power that was forced upon her the day the world split open, unveil the truth about the merciless god that raised her, and unravel the reason she was made to forget.In a rich world of old gods and Void-born magic, Gaia will walk the tenuous line two ancients have drawn in blood… or risk losing what little of herself remains in the process.Two timelines.
Two dangerous games.
One human pawn with the power to change the board.

About Me

I’m a gamer, anime/eastern drama lover, and an art school grad who majored in creative writing and cinematography.After years in the corporate black hole of interior design, I'm finally pursuing my dream of writing a book. It's been living in my head for almost a decade, and I've been writing it for a little over two years.The Unbroken Thread is more than a story to me. It’s how I’ve worked through the darkest parts of my life and found light in the act of creation.I hope this story reminds you that healing is possible, even in the unlikeliest of worlds.
