The Guardians series order

When I wrote my web page for the Guardian series, I set up the numbering to include the novellas as well as the novels, to make the series order clear. But I’ve been 1) deliberately writing the last three novellas so that they aren’t part of the main story arc and 2) have been reading a few comments online from readers starting with Demon Angel that they didn’t need to read Hot Spell first (and in fact, the storyline worked better for them if they went back and read Falling for Anthony after Demon Angel.)

So, here’s my question: Do you prefer the novellas to be included in the number ordering for a series, or just the single titles?

Because I’ll leave my Guardian page as it is — with Hot Spell first, then followed by Demon Angel, then Wild Thing — but I’d number the single titles, and not the novellas. Or, number them to indicate that the novellas come between stories. Like so:

Hot Spell (a Guardian novella)
Demon Angel (the Guardians, #1)
Wild Thing (the Guardians #1.5)
Demon Moon (the Guardians, #2)

With Demon Forged as Book #5. Whatever changes I made I’d also put in at Amazon, and so on.

Thoughts? What is more helpful to you, as a reader of a series?
