My wife Rhonda is a writer. Her latest book is called Empress Game. It's the first in a space opera trilogy that will be published by Titan Books. The book will be available in July, but you can pre-order it now on Amazon and Barnes and Noble. The cover art has just been released and it looks like this.
I think it captures the badass spirit of the protagonist quite well. I'm not an unbiased reviewer, but I've read the book and I think it's awesome; fast-paced action and science-fiction intrigue with an unforgettable heroine. Needless to say I'm extremely proud of Rhonda.
