Twilight's Birthday had to be just a party, but...
The Goddess of the Night,a Fashionista, a party-addicted, a sonic aviatress, a shy pegasus, an egghead and a farmer go to disco during one of her friends' birthday.
The cider they have drunk, however, is enchanted, making instantly drunk the ponies who drink it, thus making them lose their brakes.
Twilight will discover for the first time love, but the situation afterwards will not be easy... Rather, not easy at all
Notes:
The first chapter will not have all that is written up here, wait for the other chapters before saying that summary is misleading ;)

I must thank Chevan for the help he gives me editing :)

It has a sequel too!!: Heart in Chaos
