Howdy from NW Montana. First of all let me say I'm very appreciative of the support from Kindle readers.
A few words about A Nepenthean Solution: The original was published in 1999 and is no longer in print. Since that time, science and technology have evolved. Our understanding of the 'verse has changed much. The original premise of an impending "Big Crunch" became untenable. What to do? Rewrite with new science. 'Branes, domains, multiverse, etc.
While that story was being updated, the overall series moved on. A prequel was necessary to set-up the follow-on works. Thus the Children of Danu came to be in 2011. This story precedes A Nepenthean Solution. When the rest of the series arc was finally completed in 2019, I decided to revisit Nepenthean Solution to embed some story features hinted at in later works. During that rewrite A Nepenthean Solution and Flight of the Solar Archangel were enhanced and combined into a single work with a new title: The Grim War. Thus the seven book series was reduced by one to six. Twenty years of effort. My hope is for reader enjoyment to at least approximate that experienced while composing the nearly one-point-five million words in this series.
