The Echo awakens

Rescued as a baby from the ruins of Godric's Hollow, Eileen "Ellie" Lily Black grows up far from any truth. No one must ever learn who she really is-the twin sister of the Boy Who Lived. While the world spirals around Harry Potter, Remus Lupin hides the girl in the shadows, guarded by his own curse and by a promise to a friend he believes he has already lost.

At eleven, Ellie receives her Hogwarts letter-and is thrown into a world she should have always known. She meets Harry, unaware that he shares her blood. Yet something ties them together: the same green eyes, a strange pull in their chest whenever the other is in danger... a bond stronger than any lie.

As Eileen Black, she is sorted into Gryffindor, where she quickly finds friends-
and enemies.
Especially Draco Malfoy, who provokes her from the very first moment. He despises her name, her courage, her closeness to Harry... and yet he cannot look away from her.

Between them begins a dangerous slow-burn of sparks, rivalry, and unspoken tension-
one that threatens to divide every house in Hogwarts.
Because love between a Gryffindor and a Slytherin is forbidden...
especially when her true last name could change everything.

While Ellie slowly discovers what it means to be a Black, she has no idea she is a Potter.
And she cannot escape anyone-
not Harry,
not Draco,
not even herself.

But secrets burn.
Truths demand their price.
And Ellie is destined to choose between two worlds-
between the blood she carries
and the heart she stands to lose.
