I don't see this anywhere except on Amazon UK and Book Depository but Angus has another Outlaw Chronicles book coming out in July of 2014 titled The Iron Castle. It's still listed as unavailable and PBS doesn't have it yet but rest assured... I will be watching for it!!!

Thank you for watching Jeanne.  'Cause I'm a big fan of his.

Amazon has been completely frustrating about both #4 and #5 for me.  Available; unavailable; available....etc.

  Have a request for both Grail Knight(5) and Warlord(4) at the library but I have no idea if they will be fulfilled.

I know, Jan. I've contacted Angus about some of what is going on, especially at AZN but he has no control over it. It's the publishers! I don't know if you have an audible membership, but both Warlord and Grail Knight are available over there as well as Holy Warrior and Outlaw. Sometimes it pays to ask them since they originally had only Outlaw available. I often find that getting the audio book is the quickest way to access some books. Have you looked at Fetchbook? - they have a site that accesses all the sellers and comes up with the books available and prices to compare. You may want to try that....

As to the availability of his books, Grail Knight originally came up on Kindle as a pre order for 9.99. Then the book went up to 15+ dollars and now I find it isn't on Kindle at all - grrrrr!
