Halloween Giveaway, Yay or Nay?

I have an extra copy of How to Catch and Keep a Vampire by Diana Laurence (more info to come) and I would like to have a giveaway for it. Any ideas on how you'd like this done? I was thinking about maybe leaving a comment on here about a favorite Halloween or something of the sort and then you're entered to win. I'll randomly draw a name from a hat. If you have any other ideas please share.

Take care,
