What happens when Princess Cadance goes off the deep end? Love spreads throughout all of Equestria ... by force! Only the other alicorns can withstand the power of Cadance’s love lasers -- any other pony hit by them will drop into an immediate sexual frenzy. But Cadance has other, subtler powers at her disposal. Can Twilight help Celestia and Luna rein in their niece, resisting her powers of love long enough to vanquish her? Do they want to?
