They won’t be out until mid-2017, but here are the cover designs for the UK and US editions:
The UK edition is going to be published by Orbit, as usual, and that’s their cover on the left (or above, depending on your browser). But in the United States, the series is now moving to Tor.com Publishing; so there’s a whole new cover design coming. (To be clear: earlier books will remain with Ace, but The Delirium Brief and subsequent novels will come from Tor.)
