An omnibus with nine titles (six books and three novellas) in Julie Kagawa's Iron Fey series is available for £7.99 at Kindle UK. That's a pretty good price even if you already have a couple of them. It seems to be kind-of long term at this price, but I just noticed it now...
The titles included are:
- Book #1: The Iron King
- Novella #1: Winter’s Passage
- Book #2: The Iron Daughter
- Book #3: The Iron Queen
- Novella #2: Summer’s Crossing
- Book #4: The Iron Knight
- Novella #3: Iron’s Prophecy
- Book #5: The Lost Prince
- Book #6: The Iron Traitor
