Witness Protection Program

Emma and Lily are best friends. Always have been always will be. They've always lived opposite each other, communicating by walkie talkies whenever Emma's phone was taken away from her. Same old, same old.
One day, both girls witness something traumatizing. They witnessed a death.
So their lives turn upside down. The last thing they needed was a professional killer after them to cover up what happened!
So they both get put in a witness protection program, somewhere they have never been to.
But it turns out to be not as bad as they thought it would be, because they got put with Harry Styles and Niall Horan.
Both boys had their names changed two years ago after they witnessed a murder.
They get to know each and bladdy blah.
Two problems. One, a mass murder is after them. Two, THEY'RE IN FREAKING DALLAS.
Neither of the girls know what to do when all four of them are placed in Dallas. Harry and Niall with one couple. Emma and Lily with another.
What happens when they meet again?
Will love spark?
