~SPOILER ALERT~
If you have not read One Pony, this story won't make a lick of sense to you, at all, in any way.
So yeah, go read it, its not even long, like 16k words of decent(ish) story stuff for your reading pleasure.

The sequel to One Pony

Two years have passed since Nightmare Moon's defeat and death at the hooves of Twilight and Aon.

They now rule Equestria as a triarchy with Princess Luna. They have also gotten married, and life has been simple. But peace can't last forever, and somepony with a grudge against Luna is out to ensure the Princess doesn't live to see another year.

To top that off, Aon and Twilight must cope with a range of emotions they've never dealt with before as the sudden importance of family weighs down on them.

Can the unicorn couple save Luna, stabilize Equestria and keep themselves safe, or will haunting memories from the past tear them apart and destroy them?

And most importantly, will Luna finally be able to rise and stand in her own light, or will the shadow of another alicorn yet again be cast over her leaving her in the dark?
