Chrysalis has a scheme on Hearts & Hooves Day with Celestia's exiled alter-ego, Daybreaker, to cover Day's flank and let her show off her own. Even better, it involves Chrysalis seducing another diarch of Equestria; the ever-irreverent Princess Luna. But just because love is in the air doesn't mean Luna can't sniff out incoming trouble - or make some of her own with the debauched doppelganger.
