I received The Second Generation proof from Createspace yesterday! I got a free one last year for Stones of Cilean, and even though I didn't "win" this year and get a free coupon, I still wanted one for The Second Generation. And here it is!
I don't plan on self-publishing The Second Generation, though. It's currently with betas, and my goal is to start querying it in June. If I'm still querying it in eight-twelve months, then I'll think about self-pubbing it.
