Craving Control can be read as a standalone novel or as the first book in the Black Shamrocks MC series. It does contain very mild spoilers for Seizing Control, but not enough to ruin either book.
Soothing Suffering and Conquering Circumstances do not need to be read as part of the Black Shamrocks MC series, however they do enhance your understanding of the characters.
The Black Shamrocks MC: First Generation series (see below) is designed to be read either before or after the original Black Shamrocks MC series - or as a complete standalone series.

The Black Shamrocks MC: First Generation series can be read either before or after the original Black Shamrocks MC series - or as a complete standalone series.
The characters in this series are the parents of the characters in the original Black Shamrocks MC series and the events that take place are the catalyst for the drama that befalls the Black Shamrocks MC. While the reader may think they know what happened to the older generation after reading the original series, the First Generation series will bring an added dimension of understanding and is still full of twists and turns caused by secrets not divulged to their children.
The Centrifuge Duet is complete when read as a duet (Amnesia and Attest).
Adversary is a bonus story told from Dr. Jaxon Ray's point-of-view, and can be read as a complete standalone or as the "third" instalment in the duet. Totally contradictory advice, but the overriding recommendation is to read them one after the other in the order outlined above.
Events spoken of in Attest and foreshadowed in Adversary are depicted in full as part of Harry's story (book one) in the Full Circle Security Incorporated spin-off series (see below).
Untitled (Harry's story) (coming soon)
Untitled (Xander's story) (coming soon)
Untitled (Felix's story) (coming soon)
Invictus is part of Aleatha Romig's Fidelity World in Amazon's Kindle Worlds. It tells the story of how Felix and Ida first meet and touches upon the events that led Harry, Xander, and Felix to create the Full Circle Security Incorporated firm.
This series is envisioned as "evergreen" - meaning that Kylie Hillman will continue to write in this world forever as the FCS Inc. firm travels the world protecting both the good and the bad while dishing out their version of "what goes around comes around".
While the Black Hearts MMA series doesn't have a spin-off or prequel series scheduled, it is advised that readers keep an eye out for the unexpected appearance of some of their other favourite Australian characters as they will be appearing at the end of Conflict and making their presence felt during the chaos that invades Dissent.
