Here are a couple of links to brand new interviews with Powers that have recently appeared on-line.
The first is up at Heidi Ruby Miller's blog . Heidi sends a bunch of questions out to writers and asks them to pick and answer six of 'em. You can find out which six Powers chose by following this link .
There's a longer and more in depth interview with Powers  in the December issue of Sfrevu  - also in the issue is a review of Three Days to Never , just released in mass market paperback .
