Chapter 1 (Prologue) : Seriously Sisters - 1998

I'll bet you think you're life is complicated, right? And the chances are if you're a teenage girl like me, you either like some guy who's totally unsuitable for you, completely unobtainable or someone who your parents really hate. Am I right so far? Well, let me tell you this, you're going to think I'm lucky when I tell you that my parents love the guy that I want to be with, and he would be perfect for me, if it weren't for the fact we grew up believing we were brother and sister...

When the new boy started at school, the Giles' girls were the first to greet him. They were those annoyingly friendly children, always willing to help and be kind to everyone, no matter what. They were both always told how pretty they were and of course they liked to believe it, but they looked completely different. Xander noticed this, as these two twelve year old girls introduced themselves as Buffy and Willow Giles. Their drastically different looks led to his question...

"How can you be sisters? You don't look alike at all?" Xander frowned, and the frown only deepened when he received an answer.

"We are sisters" Buffy assured him as Willow giggled "it's just, we have completely different parents" off his look she explained, "It's kind of a long story..."

And I wasn't lying! It was a very long story back then and it's gotten even longer and way more complicated since, so I guess I should get started...
