Hi all,
This is a message that Undertow has been updated. Up to chapter 7
now. Mini-Jack makes his first apperance in chapter 3, but it looks
now like he will be a constant in the rest of the story.

Summary: When someone close to Buffy dies, she finds herself on Jack's
doorstep. Before long, events and emotions pull them into something
greater than they ever imagined.

Warning: The author has rated this fic FR18, but so far I would give
this story a pg13 or pg15 max. (I only would go to pg15 because it
deals with death and mourning.) You have some inuendo, and the
foreshadowing of a relationship between Buffy and Jack, but thats it.
