Pro tip: never try to proof an entire book, on the computer, in one day. It's bad for the eyes and worse for the temper.
And, of course, it's not like I'm twiddling my thumbs while waiting. I'm proofreading the follow-on, Awakening, and plotting the third and probably final book in this series (working title Survivors), which I hope to start writing at the beginning of July. This is going to be a tricky one. I need to show a collapsing society (Venezuela is giving me plenty of inspiration here) but I don't want to write a grim, depressing dystopia. Actually, I don't think I can; the funny keeps breaking out. I'm working on a sort of comedy of manners against the background of collapse and failure. There will be some grim bits - it's never fun when a society starts consuming itself - but I hope to balance the sadder parts of the story with scenes of my characters coping with whatever I throw at them.
Jury's still out on whether I can pull this off.
