I think you're going to have to buy it, OP. If it's not already on sadpanda, it's probably not available otherwise.

Fortunately, there's no DRM and it contains both JPGs and a PDF, so you should be able to upload it without an issue if you so desire.

it just came out yesterday, give it a few weeks and someone else will have uploaded it. If not, then buy it.
