I just got the quote back from the printers in Hong Kong who did my last two books, both of which featured some of the best printing I'd seen. Unfortunately for a number of unavoidable reasons the price has gone up considerably (about 50%). I've asked for a couple of other quotes but last time I asked Quebecor and Brenner for prices, they didn't bother writing back.
The Scary Go Round collections are a really delicate ecosystem; they take months to break even and involve as large a financial risk as I can afford to make. I don't want to do shorter collections more often so unfortunately, this might be the end of the road. This is pretty sad so I hope I can think of something.
