Each world exists in its own place, and nothing from another world exists in a different world.
 
Every series inside each separate world is standalone, and does not have to be read in any kind of specific order. When you start any series, you should start with book one, and read through to the last book. AGAIN, every series is standalone.
 
Each series or standalone novel in every world is listed in PUBLISHING order.
 
Chronological is not listed because several series within larger worlds happen at the same time at opposite ends of the country. Other books that were published later happened decades before books that published before it. Hence why each series or standalone book was written as standalone.
 
Please do not ask me for chronological order, as I will not provide it.
