The book is due out on September 20th, and you can pre-order it in paperback or on Kindle here, among other places.
I shouldn't say too much about this one just yet, but I will say that it was immensely fun to write, and I think it's better than The Lazarus Gate. There, I said it. The Iscariot Sanction is a prequel to LG, and set on the Otherside, just for maximum head-tripping. This means we get to learn a bit (a lot) about why the Othersiders' world is so terrible, why they felt the need to build the Lazarus Gate in the first place, and what terrible foes Apollo Lycea must face on a daily basis.
The cool thing about this book (I think) is that it can be read before The Lazarus Gate without spoiling too much, but if you read it afterwards you get that Eureka moment when you realise just what some of the 'baddies' were up to...
Anyway, more on that at a later date. For now, know that you have just over a month to finish reading Lazarus in time for this shiny new release...
