Pumpkin Martini

I just saw a martini posted so I thought I should post my favorite one... this is originally from Colleen Graham and Your Guide to Cocktails. "The Pumpkin Martini has long been a favorite cocktail for fall. Although it has recently become difficult, well impossible, to find pumpkin schnapps or any pumpkin liqueur. Until another pumpkin liqueur comes on the market again you can substitute pumpkin spice syrup or pumpkin puree."
