When ice meets fire, something is bound to melt. At a start of her fifth year of Hogwarts, the new girl never expected her biggest problem to have a smirk, a Slytherin tie and a heart carved from ice. Mattheo Riddle is everything she's supposed to fear - cruel, dangerous and heartless. And she is everything he was taught from young age to hate - soft, kind and pure. They are bound to be enemies, but as sparks fly and secrets unravel, they'll both learn that even the coldest hearts can melt.

After the accident at Wickery Bridge that claimed her parents' lives, Celeste Gilbert's world shattered into pieces. But unlike her twin sister Elena, who retreats into her grief just trying to stay afloat, Celeste reacts with rage and a heart of steel. She is the backbone of the Gilbert house, the one who protects Jeremy and isn't afraid to look the darkness right in the eye. Everything changes when the Salvatore brothers arrive in town. While Elena is drawn to the mysterious Stefan, Celeste finds herself in the crosshairs of the unpredictable and dangerous Damon. Between them, a spark of lethal defiance and attraction ignites instantly. Damon sees something in her that no one else has: a wild flame, a determination that refuses to break for anyone. But Celeste is more than just Elena's twin; she is a soul bound to an ancient "debt," a contract rooted deep within her family's past-a secret that must remain buried. In a Mystic Falls where vampires return to reclaim what is theirs, Celeste must fight for her family and her very soul. Because Celeste is no one's shadow. She is the fire that burns in the dark.
