Water, Ice and everything cold

Hello. My name is Eve. I live in a world of superheroes. People started getting powers back in the 80's and now half the population had them. I am an advanced hydrokinetic. That means I can make, control and destroy water, ice, snow and steam. People can also have 2 powers if they are both primary like control of only wind and only fire or being able to teleport and heal. So this is my life going to a boarding school for supers.
