These are the new worlds: The Verduran Pentology. The final two volumes and a boxed set will be available by November, 2021. You can check them out in more detail here.
These are the old worlds. At least, though they’re in what was then called the ‘new world’ in the world we live in, they’re about a time about two-hundred years in the past in our world, and as close to the reality of that time and place as I can make them.
This is the ‘Young America’ Series. I’ve written the first two and am working on the third. Current planning calls for a number four and a number five. Book 1 takes place in 1781-2, Book 2 takes place in 1782 through 1789, Book 3 takes place in 1790 through 1804, it looks like Book 4 will deal with 1805 to 1815, and Book 5 from there to 1825. That’s when James Monroe, the last of the founders, ended his presidency. Go to the ‘Young America’ page to check them out by clicking here.
