Shades of Empire's last hurrah as a free Kindle book is today. It is now free in the Kindle store in the US, the UK, Germany, France, Spain, and Italy.
If you're interested, this book is kind of an old-fashioned space opera, if that's not an oxymoron. It's got a princess, an evil emperor, a damsel in distress, a couple of heroes and some courageous women, too. Parts of this story are rather like the story of Caligula, which will tell you it's more R-rated than G-rated. Go to your Kindle store and grab it!
