I finished the first draft of Kingdom of Ashes back in summer 2014. After that the manuscript has gone through numerous revisions and has evolved beyond recognition. The story kept growing, until one of my editors suggested that there is enough material for two books. After some thinking I decided the story indeed works better split in two, so now you’ll be getting two novels, Kingdom of Ashes, and Men and Monsters. This means I still have a lot of editing to do to make sure you don’t feel like you’re reading half a book, but I believe I can get the books ready for publication early 2016 and 2017 respectively.
Note that Nightfall is still an ongoing series, and I expect 6-7 books total. I know some readers are hesitant to start a new series, out of fear of series fatigue, and would like to know if the first book can be read as a standalone. To be honest with you, Kingdom of Ashes and Men and Monsters together can definitely be read as a standalone, without reading the following books. However, I wouldn’t recommend reading Kingdom of Ashes without Men and Monsters since a few questions are raised in the first book and answered in the second. You can give it a try, but I’m not sure if it will be satisfactory enough. I just wanted to let you know before you decide to jump into the series 😉
