My friend has been interested in N.O.W and can't find a place to buy the book (he did found the preview but that's all). He asked to ask around here to see if it's still being written or was it just for the Kickstarter donors.
N.O.W. isn't available, yet. I believe it's only in the early draft phases and still needs to be playtested. Some of the material can be found in the WOIN reference document at woinrpg.com.
