We Borrow The Light by G. Bailey

I was their perfect student—now I’m going to bring Bloodstone Academy down.

Every generation of the Daygan family went to Bloodstone Academy, but it was all a lie. I was taken as a baby, manipulated and used, my memories and time stolen. Now they want me to marry Hemlock Mercury. Over my dead body.
Mazikeen Lycidas, Kane Ardian, Black Ashveil, and Valeron Drexan are my bonded. More than that, they are my fated mates—and I am half dragon, fire and fury incarnate. I will burn through every barrier to bond with them this year—again—and this time, I will not have my memories taken from me. No one will tear us apart.
Spells are going to save us, the Umbral Authority is going to fall, and shifters will be freed. Vengeance will be mine.
This is my fourth year at Bloodstone Academy, and it will be my last.
I remember—and I won’t forget. And neither will they.
