Series background & context
Cyborg Space Exploration follows the crew connected to the Reckless, Vector's ship, as they travel beyond familiar territory. New planets mean new people, new dangers, and new chances for cyborg warriors to meet the women meant for them.
It is an adventure series as much as a romance series.
The books take place after Cyborg Sizzle, but each main story is structured as a standalone with its own couple and happy ending. Readers can begin here without knowing every earlier event, then pick up the larger history through the crew's conversations and shared loyalties.
Choosing Chuckles opens with Chuckles answering a distress call from Bettina, a human woman who has reasons of her own for luring ships into danger. Doc’s Orders continues the travel-and-rescue setup, while Dominance And Dissent follows Dissent and Greer as a search for freedom turns into a fight against an armed enemy. Passion Surge is a lighter companion story about a cyborg medic and an exhausted single mother.
Later installments, including North Bound and Testing Truth, keep the crew moving through unfamiliar territory. The atmosphere stays dark and sometimes violent, but the books also make space for found family, caregiving, strange local creatures, and warriors learning that protection is not the same as control.
The universe is always bigger than the map.
Read in order if you want the full crew experience. If you prefer to sample, choose the couple or trope that catches your attention and return to the others afterward.
