Since most of my works are within one of two universes, I figured I'd make a list for ease of reading.  The Kattyverse will get two, one for the order in which they were written and the other chronological.  Though if you decide to read them chronologically, keep in mind my skills as a writer have evolved between book one and the latest book.  All of them are written to stand alone so you could potentially start anywhere you like.
How they were written:
Moon Rise
Midnight Rendezvous in the MMO
Moon's Reign
The Moons Light
Soldiers Hostage
Blood Brothers
Silent Intrigue
The Trouble with Slaying
In the Dragon's Keep
Spells and Daydreams
The Maiden's Dragon
Kintsugi
Guardian of the Lost
Moon's Rite

Chronologically:
