Fate/Hollow Fake

Fate/Hollow Fake is a two-part Fate Stay Night Alternate Universe fanfic/Quest hosted on Sufficient Velocity by ZerbanDaGreat.

The Holy Grail War has come once again to Fuyuki City, but in a way that nobody was expecting. The story follows Tamiko Kurosawa, a stressed out barista whose life is changed forever when she and her friend Yuko unwittingly are plunged head first into the secret world of mages and servants. Barely escaping death at the hands of a Servant for witnessing too much, Tamiko and her newly summoned Servant, Lancer, must navigate their way through the war, and try to figure out how to keep themselves, let alone those they care about, alive until the end of a fight that seems to make less sense the longer it goes on.

The story was dictated by the choices of its readers, and balances its time between character interaction during the day and grail war activity in the evening.
