Pre-orders are now open for Death to the Witch-Queen at Kobo & iBooks. A pre-order on Amazon will follow next week.
If you're into SF that's lighthearted in tone but still epic and capable of taking turns into darkness, like Firefly or Guardians of the Galaxy, there's a good chance you'll enjoy Witch-Queen. It has no pretensions, no melodramatics, no existential angst, no deep philosophizin', no fancy literary references (unless you count maybe a teeny bit of Wizard of Oz...), no talky-talky plot. It's just a fast-moving good time full of what I think are some pretty original ideas.
