Galaxy Unknown Books in Order

Where to Start with Galaxy Unknown

If you are planning to dive into Thomas DePrima's expansive sci-fi universe, the best starting point is undoubtedly the very first novel, A Galaxy Unknown (2008). The series is highly serialized, tracking the career progression and personal growth of protagonist Jenetta Carver. Skipping ahead or reading out of order will spoil major plot points, military promotions, and the evolving political landscape of the Galactic Alliance.

The Core Series: A Galaxy Unknown

The main series follows Jenetta Carver as she rises through the ranks of Space Command. Starting as a stranded ensign who wakes up eleven years after a spaceship disaster, she quickly becomes one of the military's most tactical and feared officers. The core storyline spans twelve published novels.

Recommended Core Series Reading Order

To follow Jenetta's career chronologically and avoid confusing character developments, we recommend reading the main series in the following order:

1. A Galaxy Unknown (2008) – Jenetta is introduced as a resilient young Ensign who survives a long sleep in a life pod, only to find the galaxy overrun by raiders.
2. Valor at Vauzlee (2010) – Promoted to Lieutenant Commander, Jenetta faces a massive pirate armada in a desperate convoy defense.
3. The Clones of Mawcett (2010) – Still a Lieutenant Commander, Jenetta deals with political intrigue, clones, and hidden agendas.
4. Trader Vyx (2010) – Jenetta works alongside covert operations, introducing black-market arms dealer dynamics.
5. Milor! (2010) – Now a Captain commanding a key base, Jenetta must prevent an all-out war involving a hostile insect-like alien race.
6. Castle Vroman (2011) – Jenetta faces complex security threats and defense missions.
7. Against All Odds (2011) – High-stakes tactical military battles put Jenetta's strategies to the ultimate test.
8. Return to Dakistee (2011) – Jenetta returns to a familiar planet to handle new crises.
9. Retreat And Adapt (2013) – Space Command must adjust to evolving threats as political situations deteriorate.
10. Azula Carver (2015) – Thrust into the role of Admiral of the Fleet, Jenetta handles massive organizational responsibilities.
11. Changing of the Guard (2017) – A shift in leadership and strategic defense priorities within Space Command.
12. The Invasion Begins (2018) – The final published book in the core series, ending on a major cliffhanger.

The Early Books Discrepancy (Chronology vs. Listing)

Readers should be aware that book platforms and retail sites often disagree on the numbering of the early novels. For instance, Goodreads and Amazon list Valor at Vauzlee as Book 2, followed by The Clones of Mawcett as Book 3, Trader Vyx as Book 4, and Milor! as Book 5. However, some publisher databases and the local library records place Milor! second and Valor at Vauzlee fourth.

If you track Jenetta's military rank, the Goodreads/publication sequence is the most logical: she is a Lieutenant Commander in Valor at Vauzlee and The Clones of Mawcett, and has been promoted to Captain by the events of Milor!. Reading Milor! second disrupts this rank progression, so we suggest sticking to the Goodreads order for the best narrative experience.

The Spin-Off Series

Thomas DePrima has expanded the Galaxy Unknown universe with two distinct spin-off series that focus on different aspects of Space Command. While these can be read independently, they enrich the main narrative and are best tackled after you have read at least the first few core novels.

AGU: Border Patrol

This subseries shifts the spotlight to Sydnee Marcola and the gritty, day-to-day operations of the Space Command Border Patrol. The series is best read in publication order:

• Citizen X (2012)
• Clidepp Requital (2014)
• Clidepp Deja Vu (2017)
• Lieutenant Marcola (2019)

Chronologically, the events of Citizen X occur roughly before the events of the eighth core book, Return to Dakistee, which is evidenced by the specific makeup of the Admiralty Board members mentioned in the text.

AGU: Space Command Intelligence

Focusing on covert operations and intelligence gathering, this subseries currently has only one published installment:

• The Star Brotherhood (2013)

Connected Standalones: The Colton James Series

For readers who want to explore more of DePrima's writing within the same setting but with a different flavor, the Colton James series offers a private investigator perspective. These books are standalones and can be read at any time:

• A World Without Secrets (2014)
• Vengeance Is Personal (2016)

What to Know Before You Start

DePrima's work is heavily inspired by classic naval fiction like C.S. Forester’s Horatio Hornblower, translated into a space opera setting. This means you will find a strong emphasis on military hierarchy, tactical space battles, and political maneuvering. While some readers note that Jenetta Carver can occasionally feel like an 'invincible' protagonist who rarely makes mistakes, the fast pacing, addictive storytelling, and clean sci-fi adventure tropes make this series a beloved hidden gem for space opera enthusiasts.

Additionally, fans should know that the twelfth book, The Invasion Begins (2018), ends on a cliffhanger. As DePrima has not published new works in this universe since 2019, the story remains incomplete, but the journey up to that point is highly regarded by fans of military science fiction.
