But when she goes to school to try to be normal-ish she meets her twin once again, and the silent loner who everyone want to be friends with. What happens when she meets her twin again will her cold shell start to shatter enough to let him in again? And what about the loner? Will she get him to talk? Or will he capture her heart first, in the end it will be up to the two boys to melt the ice princess to the warm and kind fire princess that her twin knew her to be.
