Reunited

My name is Alexis Weber. When I was born my parents had already been married and divorced. My father William then got married to a women named Gina. I never got to know my fathers last name for some reason. Apparently he has two sons too. One is my age, a few months older than me and the other is 12. Right now I am 14. Basically I have 2 stepbrothers as if now but I never knew their names, where they live, their last names, anything. My mother Mary Weber will not talk about them at all. She never gave me a single piece of information about my biological father other than his first name and his wife's first name. Nothing more. But one day, one thing everything changed. The truth?
