The Speechless secret

Prologue:

I jolted out of bed and ran into the hall. There's smoke everywhere. I looked around not sure where to run, when a hand grabbed mine. My mother. Her other hand clutched my twin brother. She ran with us out of the house, told us to stay put and ran back in. As she ran i yelled "mummy!" and made to run after her but my brother held me back. I guess she went to get my father and younger sister but ill never know cuz when she ran back in the house collapsed and I never saw her again. Mummy. The last word I ever spoke. After the fire I never spoke again. Its been twelve years. My mothers parents took me in and my brother got adopted. When i turned 18 my grandparents bought me my own house i guess i was too much of a burden. I never lost touch with my twin brother. He would always Skype me and sing to me everyday but now he hardly has time. My brothers name is Liam. Liam Payne. It's not our real last name. His adoptive parents made him change it. Everything everybody knows about him is a lie. Nobody except me knows he has a sister who can't speak I'm just his... Speechless secret.
