What's up with the jump gates?

I get this question from time to time, so I thought I'd post the answer and save email time for others (and myself): wait and see.

Yup, I'm not gonna tell you. In due time (right around 10 or 12 books into the series, maybe a tad earlier), we'll start to learn the secrets of the jump gates. Until then, however, we can only enjoy them--and wish we had them in our world.

Speaking of enjoying, I must get back to Overthrowing Heaven, which I'm having quite a good time writing. The game is afoot.
