I was on the exact same quest as you about 6 months ago. Loving sandalwood and most Lutens fragrances it sounded perfect for me. I was able to get a decant from someone though he no longer has any. You can find decants on ebay sometimes. Its impossible to order this for delivery to the US as its part of the Serge Lutens "exclusive" line only sold in the boutique in Patis and only shipped within Europe. The best you can do is have it shipped to a friend in Europe and have that friend ship it to you.
As for the scent itself yes it starts off smelling like intense spices and cumin which totally turned me off as this is what I grew up eating. Eventually this one takes a swet syrupy turn with some coconut showing up. The sandalwood doesn't truly show up til the drydown which is the nicest part to my nose. While this fragrance is interesting its not something I want on my skin. Sorry I don't have my decant anymore. Good luck in tracking some down.
