Sorry to have to relate this, but these things do happen.
My initial plan this year had been to have Kingdom Asunder out by now. Whilst it's 95% done and I will be trying to release it this year I can't guarantee that for a few reasons I won't bore you with. However, I will be working hard to whip it into shape with a potential release late in 2015.
My last book (Temple) was out in 2013 and I was looking forward to having 1-3 books out this year, including my first solo efforts via a publisher, but, to paraphrase the trailer to Skyrim, my defeat is merely a delay.
There is good news elsewhere. Sir Edric's Kingdom (3rd instalment in the series and larger than Temple and Treasure combined) is coming along very well. I expect the text to be complete this year. I've outlined a 4th Sir Edric adventure, as well Traitor's Prize (the sequel to Kingdom Asunder) which I've also started to write.
So, here's the state of play:
Kingdom Asunder - possibly released Q4 2015 [if not, it'll be probably Q2 2016]
Sir Edric's Temple, Sir Edric's Treasure - planned for March 2016
Sir Edric's Kingdom - 95% done, hope to get the text completed this year
Traitor's Prize - fully outlined, written perhaps 10%
Sir Edric and the Plague - fully outlined
Anyway, I just wanted to keep everyone up to date with where things stand.
