Lullaby For a Princess

"Lullay moon princess, goodnight sister mine
And rest now in moonlight's embrace
Bear up my lullaby, winds of the earth
Through cloud, and through sky, and through space

Carry the peace and the coolness of night
And carry my sorrow in kind
Luna, you're loved so much more than you know
May troubles be far from your mind
And forgive me for being so blind"

After getting into a major car accident at the age of two Regan has suffered from memory loss.

After getting into a major car accident at the age of nine, Niall Horan had lost his little sister.

Can they find each other? Will Regan remember him? What has happened over the past ten years?
