This whole self-publishing adventure has been a learning process from day one. Covers are the first and best marketing tool to get people interested in taking a chance on your book, and while I loved the covers when I first launched with them, after living with them for a while I realised they don't do much to convey the kind of books they are.
After Sync comes out I'm going to retire the old covers and launch a new set.
I had a hard time trying to come up with a concept that immediately conveys the twisty cyberpunk action of the series, but I was browsing Reddit and came across the artwork of Mike Winkelmann (AKA Beeple). I knew immediately that I wanted to somehow incorporate his amazing designs into the covers for Lost Time and reached out to him and asked if I could license a video he created to use as artwork for a new set of covers. Not only did he immediately agree, but didn't even charge me anything.
He's super talented and a super nice guy. Go check out his work at http://www.beeple-crap.com/.
