Is it a stand-alone or part of a series?

[Long Cut]

It's part of a series...it's the inaugural tome in a series she calls The Lives Of The Mayfair Witches

It includes, in order, the following:

The Witching Hour

Lasher

Taltos

It combines with The Vampire Chronicles in these, in order:

Blackwood Farm

And concludes in Blood Canticle

If you don't want to read all those, just read Witching Hour. It stands very well on its own. Be forewarned, though, you'll want to read the sequel anyway.
