(OPEN) "Flagstone Fire Ranch" Series

[Chelsea]

I am just finishing reading Her Alien Husband and at the beginning it had a note saying it was connected and best enjoyed along with a couple other books so I was wondering if they qualify to be grouped together as a secondary series even though they all also belong to other series? (I included the note with each book linked to it's page.)

Flagstone Fire Ranch Reading Order:
His Human Runaway (Thorn & Mica)
Her Alien Husband (Burl & Lucy)
His Human Rebel (Rake & Stella)
**Sten Flagstone and Erid Loadstone will have their stories in 2025!

Thank you for your help whether this counts as a series or not.

Have a great day.
