I've not really ever gotten that into Urban Decay for some reason, but I do want this:
The link has pictures - it's an Urban Decay Book of Shadows with an Alice in Wonderland theme. The Sassi Sam blog says that it's a Sephora exclusive launching on 28 December. Fingers crossed it's only Sephora exclusive in the US, and that it is going to come to the UK too. The ladies on makeupalley.com (where I first saw the link to the Sassi Sam blog) are going slightly bonkers over the idea already.
Edit: Urban Decay have put a message on their Facebook page saying that it won't be out in Sephora on 28 December, but no further news of the launch yet. For more info on the UK release, see this post on the marvellous British Beauty Blogger blog.
