Hm... first; i'd like to say im a new reader and i LOVE your story!!
Second; yes; i think it would be better to change it to... maybe 18 or 19; just so it doesnt get all... ackward and stuff :D
Third; as for names: Autumn(i love this name for some reason) Heather(for something original) or maybe Kazmra(for something exotic)
Hope i helped!! And keep up the AWSOME, AWSOME, AWSOME story!!!!!!!
Luv,
Me
