Starlight and Twilight

When two twin sisters, Starlight and Twilight, are deserted on an island after a shipwreck, they find themselves having to fend for themselves.

But on their fifteenth birthday, a sea witch attacks them and they start to uncover secrets that have been long buried and locked away.

Their mother is an ancient spirit and is a second timer, trying to help them along their quest to save Earth.

Two boys, Fathom and Silver, princes of the long lost Atlantis, join in to help bring evil to its feet.

But the journey isn't as easy as they hoped. Chaos is stirring in He shadows with its minions that will stop at nothing to tear these Atlantians apart, piece by piece, and serve their master.

Will the sisters survive in these times of chaos?

And when there is love, how will any of them survive. There isn't time for live in times of darkness, right?
