“It’s hard to avoid noticing that J.C. Gabel, a tall, almost burly transplant from Chicago, is — among other things — a bit of a ranter. … But the difference between Gabel, 42, and most people who declaim loudly on the patios of bookstores is that a) he’s generally — or at least arguably — right most of the time and b) he’s managed to put his money where his mouth is. … Surviving in the current publishing climate is impressive; thriving and expanding is almost bizarre. And Gabel and company have done it.”
