MLP Romance Reading - All That Lingers (Cadence x Sombra)
Description YT
The night that Cadance discovered the ghost of King Sombra lurking in the Crystal Palace should have been the worst of her life. Her greatest enemy is now lingering in her own home... and she knows that she's going to get to the bottom of this.
There hasn't been anything going on in the palace for a long time, and the tyrant's ghost will only prove to be a problem... won't it?
