Niall's secret twin {Louis Tomlinson fanfic}

Elizabeth Stevenson-Horan is the secret twin of Niall Horan, member of the famous boy band One Direction. In fact, she is such a secret twin that even Niall and Elizabeth didn't know about each other for the first thirteen years of their lives. Now, though, the two are so close it's impossible to tell that they were ever apart.

However, Elizabeth isn't known to the public eye. As far as any of the fans know, there are only two Horan's and both are boys. The boys don't know about her either. Niall has always wanted to introduce them but Elizabeth is too scared because of her awful past with boys. Since then, she has never trusted any guy outside of her family.

But what will happen when the five finally meet and Louis finds himself stuck in the middle of the two twins?
