I purchased two copies a few weeks ago from Unbound here: https://unbound.com/books/cains-jawbone-paperback/ https://unbound.com/books/cains-jawbone-paperback/ It shipped from overseas and, as usual, was stuck in US Customs for about a week, but this was in the run-up to the holidays. Might be faster now.
