I found the time to set up the pages for the series on Amazon, where you can now buy the series with a single click (at least 3 out of 4, Silvery Earth probably has too many books, LOL!). Check them out!
Silvery Earth (44 books)
Star Minds Universe (32 books)
Vampires Through the Centuries (10 books) – soon to be 11
Future Earth Chronicles (10 books) – will be 12 in January
You can even hide the books you already have in your Kindle library, and buy the rest in bulk… Happy reading!
