The Invisible Mark Pt1

Teddi Ryan was never the villain they made her out to be. Born into a proud Pureblood family, a member of the Sacred Twenty-Eight, and sorted into Slytherin House, Teddi quickly learned the world had already made up its mind about her. But beneath the surface - behind the polished manners and sharp wit - was a girl with a heart too stubborn to hate and too brave to follow orders she didn't believe in.

Raised to look down on others, Teddi's loyalty was only ever to those who truly earned it: her best friend Daphne Greengrass, her beloved brother Wyatt, and the handful of students who saw beyond House rivalries. But when Teddi discovers her parents have pledged themselves to Voldemort - and expect her to do the same - she faces an impossible choice: obey, or risk everything.

Forced into the heart of the darkness, Teddi walks a dangerous tightrope - attending secret meetings at Malfoy Manor, pretending loyalty to the Dark Lord, and manipulating those who would call her friend. Only Draco Malfoy sees through her mask, and the two form a bond that turns to a fierce, forbidden love. But betrayal comes at a steep price.
As the war claims those closest to her - first Cedric Diggory, then her beloved brother - Teddi makes a choice: she will not be a pawn. She will fight back.

Training in secret under Dumbledore's guidance, mastering spells even the Ministry had forgotten, Teddi becomes the Order's invisible ally - saving lives from the shadows, protecting the trio's path to victory, and defying death itself.

When the final battle comes, Teddi must stand between her parents and the girl they were ordered to kill - Hermione Granger - forcing them to choose between blood and blind loyalty. And when the fate of the world hangs in the balance, it is Teddi who shields Harry, who saves Draco, and who ensures Voldemort's fall - even if no one ever knows.

She doesn't want fame. She doesn't want thanks.
Teddi Ryan only ever wanted to be free.
