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.
