Quite an intriguing start, I'd very much like to read more. :)
Congrats and kudos!

cool

I like what you have so far, however, you do have several spelling errors in these first two chapters. Also why isn't Xander using the Internet to look for his family? More soon please

I like this.
Please continue.

Great story, brilliant interactions poor Xander that's a lot to find out about in your dreams, please update soon.

interesting plot idea. Usually if he's related to someone it's throug the Halliwell line. Having be a Bennett but not a Halliwell is really neat. No powers of course (unless his mother was a witch, which is possible given that a demon apparently killed her --after all, why was she killed? and all that)---
So this would come as quite a shock to the charmed ones & family... they have a brother. One also wonders if the Book of Shadows has an entry on slayers... or if Willow should have gotten a whitelighter. (too much to hope that Tara might be one now)

Interesting start.
I don't think anybody's done a "little half-brother Xander" to the sisters before.

Keep going!

Good start. Keep going!! So how is he related to them?

Very interesting start!

Short, so there's not a lot to go on but a good start and I'd like to see where you take it.

One question: you wrote "He had often dreamed of his adoptive parents coming to take him away"...did you mean his REAL parents coming to take him away? Why would he be living with the Harris' if he already had other adoptive parents?
