Olivia Thorn Books in Order (Updated April 14, 2026)

Olivia Thorn is, at least from the currently verifiable bibliography, a very focused author rather than a heavily branched one. The visible catalog is built around a single dark-romance mafia series, Mafia Kings, with one book per central male lead and an ongoing connected family storyline running underneath it.

That makes this page unusually straightforward. There is no maze of side series to sort out. There is one main line, and the right reading order is simply to start at book one and keep going.

If you only want the answer

Read Mafia Kings in publication order:

1. Dario
2. Adriano
3. Massimo
4. Lars
5. Roberto
6. Valentino
7. Niccolo
8. Giorgio
9. Marcello when available

For almost everyone, Dario is the correct starting point. Even though each book centers on a different couple, the later entries clearly build on the Rosolini family world, ongoing rivalries, and consequences from earlier books.

The shape of Olivia Thorn’s catalog

Instead of splitting this into “best route,” “chronological route,” and “publication route,” it is more useful to say it plainly:

1. Main continuity: Mafia Kings
2. Best starting point: Dario
3. Newest released book: Giorgio
4. Next listed book: Marcello

Because the bibliography is so compact, the main question is not “Which series first?” but “Can I jump in later?” In theory you could sample a later book for the romance, but in practice the series pages and descriptions point to an increasingly connected mafia-family arc. The safest advice is to read straight through.

Mafia Kings books in order

1. Dario (2023): The first Mafia Kings novel and the foundation of the whole series, introducing the Rosolini family world through Alessandra and the man who changes her life the moment he enters it.
2. Adriano (2023): The second book, continuing the family-centered mafia setup and expanding the series beyond Dario’s opening story.
3. Massimo (2023): The third installment, still inside the same Rosolini-centered continuity, and best read once the first two brothers’ stories are already in place.
4. Lars (2024): A second-chance and enemies-to-lovers turn in the series, bringing in a Special Forces past, British intelligence ties, and a heroine who may have to destroy the family Lars now serves.
5. Roberto (2024): A Hong Kong-set entry involving missing family money, obsession, and a BDSM-club owner heroine, widening the series geographically while keeping the Rosolini stakes central.
6. Valentino (2024): An arranged-marriage conflict book, where a fling with a kitchen worker collides with family duty and a match to another Cosa Nostra family.
7. Niccolo (2025): The consigliere’s story, positioned after the earlier family books and tied directly to the wider mafia war surrounding Dario and his brothers.
8. Giorgio (2026): A loyal Rosolini foot soldier falls for a woman in Florence while a new threat rises from Naples, and the aftermath of book seven begins to reshape the entire family’s future.
9. Marcello (2026): The ninth listed Mafia Kings book and the next scheduled entry, best treated as the continuation of the same main series once released.

The order I would actually recommend

Not every “books in order” page needs a complicated answer. For Olivia Thorn, the practical recommendation is just this:

New reader route

1. Dario
2. Adriano
3. Massimo
4. Lars
5. Roberto
6. Valentino
7. Niccolo
8. Giorgio

Catch-up route for readers starting now

1. Dario
2. Adriano
3. Massimo
4. Lars
5. Roberto
6. Valentino
7. Niccolo
8. Giorgio
9. Marcello once it is out

There is no strong reason to invent a separate “chronological order” here. Publication order already appears to be the intended reading experience, and the later books reference ongoing family and war-related developments that make more sense in sequence.

Where should you start?

That depends less on subgenre preference and more on how much context you want.

1. Start with Dario if you want the full connected experience and do not want to miss the Rosolini family setup.
2. Start with Lars only if you already know you prefer a second-chance romance with espionage edges and are willing to enter a series midstream.
3. Start with Valentino if arranged-marriage tension is your main draw, but it still works better after the earlier books.
4. The strongest recommendation remains Dario, because every later starting point trades away some family context.

Do Olivia Thorn’s books need to be read in order?

Yes, more than the naming convention might first suggest.

A title like Roberto or Valentino can look self-contained, and each book does spotlight its own couple. But the verified series pages describe a shared mafia family, repeated references to Dario and the Rosolinis, an ongoing mafia war, and consequences carrying from one book into the next. That is enough to make publication order the safest reading advice.

Are there novellas, spin-offs, or separate continuities?

I did not find a second clearly verified Olivia Thorn series on the main bibliography sources I checked. I also did not find a confirmed novella or side-story list that needs to be inserted between the numbered books.

For now, the stable reference answer is simple: Mafia Kings is the main Olivia Thorn bibliography currently visible.

FAQ

What is the best Olivia Thorn book to start with?

Dario. It is book one, and it introduces the family and world the rest of the series uses.

They look partly standalone at the couple level, but the broader family and conflict structure clearly continues across the series, so reading in order is the better choice.

What is Olivia Thorn’s newest book?

The newest released book I found is Giorgio.

Is there an upcoming Olivia Thorn book?

Final recommendation

Olivia Thorn is one of the easier authors to sort into reading order because the catalog is not fragmented. Read Mafia Kings from Dario through Giorgio, then add Marcello when it releases. For this author, the simplest answer is also the best one.
