How to Read the Titan Series: Recommended Reading Order
If you want to experience the adrenaline-fueled operations of the Titan Group and the romance that blossoms in the line of fire, the best way to read the series is in publication order. While the books are largely written as standalones, character arcs, relationship statuses, and background agency conflicts evolve over time. Following the publication order ensures you avoid spoilers and witness the team grow from a tight-knit core group into a sprawling private security empire.
Here is the recommended reading path for Cristin Harber's core Titan series, including the key novellas that bridge major character arcs:
- Winters Heat (2013) – Colby Winters & Mia Kensington
- Sweet Girl (2014) – Cash Garrison & Nicola Hart (Prequel / Book 1.5)
- Garrison's Creed (2013) – Cash Garrison & Nicola Hart (Book 2)
- Westin's Chase (2013) – Jared Westin & Sugar / Lauren (Book 3)
- Gambled (2013) – Brock Gamble & Sarah Gamble (Book 4)
- Chased (2013) – Asher McIntyre & Jenny Chase (Book 5)
- Savage Secrets (2014) – Rocco Savage & Caterina Cruz (Book 6)
- Hart Attack (2014) – Roman Hart & Beth Tourne (Book 7)
- Deja Vu (2017) – Cross-character bridge novella (Book 7.5)
- Black Dawn (2015) – Parker Black & Lexi Dare (Book 8)
- Sweet One (2016) – Cash Garrison & Nicola Hart (Book 9)
- Live Wire (2016) – Jared Westin & Sugar (Book 10)
- Bishop's Queen (2016) – Bishop O'Kane & Ella (Book 11)
- Locke and Key (2017) – Locke & Cassidy (Book 12)
- Jax (2017) – Jax & Seven (Book 13)
- A Very Titan Christmas (2025) – Holiday Special
Publication Order vs. Chronological Order Caveats
For the most part, the chronological timeline closely mirrors the publication sequence. However, there are two primary exceptions that readers often debate: the prequel novella Sweet Girl and the holiday special A Very Titan Christmas.
Sweet Girl tells the college backstory of Nicola Hart and Cash Garrison, taking place before the events of the series. While you could technically read it first, doing so might ruin the mystery of Garrison's Creed, where Nicola is reunited with Cash after being presumed dead. Reading Sweet Girl after Winters Heat (as Book 1.5) or even right before Garrison's Creed gives the reunion far more emotional weight. It fills in their romantic history and explains how Nicola ended up in witness protection.
Deja Vu (Book 7.5) and A Very Titan Christmas are shorter bridge novellas. Deja Vu is highly recommended before diving into Black Dawn because it sets up the overarching suspense thread that ties the later books together. A Very Titan Christmas acts as a cozy, high-stakes holiday wrap-up that is best saved for the very end of your core Titan read.
Who is Who in the Titan Group: Key Couples & Plot Focus
If you're looking for a specific trope or want to know what each book focuses on, here is a quick breakdown of the core Titan novels:
- Winters Heat: Introduces the Titan Group. Colby Winters, a hardened operative, is sent to rescue military psychologist Mia Kensington. It features high-stakes cartel danger and instant-attraction chemistry.

Expanding the Universe: Delta, Aces, and Spin-offs
Cristin Harber didn't stop with the Titan Group. She built a massive, interconnected universe that includes several spin-off series and collaborative projects. If you want the full "Team Titan" experience, you can branch out into the following directions:
The Delta Series
The Delta team functions as the "ghost" team for the Titan Group, executing off-the-books operations that Titan can't touch. While Delta operates in the same timeline and features guest appearances from Titan characters, it can be read independently. The reading order is: Delta: Retribution, Delta: Revenge, Delta: Rescue (a crossover novella), Delta: Redemption, and Delta: Ricochet.
The Aces Series
Following the conclusion of the main Titan line, the Aces series focuses on a new set of military operatives and security specialists. This series includes: The Savior, The Protector, The Survivor, The Guardian, The Defender, The Bodyguard, and The Saint.
Titan Protectors
This newer spin-off series focuses on personal bodyguard and close-protection details rather than military-grade black-ops. It is a fantastic starting point for readers who prefer personal-security tropes. The books include: Hide and Seek, Run and Hide, and Lost and Found.
The Only Series
If you prefer New Adult contemporary romance over military action, the Only series (beginning with Only for Him) runs parallel to the Titan universe. However, it focuses on coming-of-age themes and a single couple's journey, so it is highly recommended to read this series entirely on its own from start to finish.
Titan World Collaborations
Harber created "Titan World," a shared-universe project where she invited other romantic suspense authors to write standalone stories featuring Titan Group characters, locations, and lore. These collaborations are perfect for readers who finish the main series and want to spend more time in this high-stakes world.
What to Know Before You Start
Before you jump in, keep these practical tips in mind:
- Standalones with a Catch: Every book in the main series has a self-contained romance with a satisfying happily-ever-after (HEA). However, the overarching plotlines involving the Titan Group's enemies, corporate growth, and government conspiracies carry over. If you read them out of order, you will know which characters survive and who ends up married.
- Pacing and Tone: The series is known for its fast-paced, action-movie styling combined with steamy romance. Expect alpha heroes who are protective but respectful of the strong, capable heroines who fight right alongside them.
- Start with Winters Heat: Although Sweet Girl is labeled Book 1.5, we strongly recommend starting with Winters Heat. It does the best job of introducing the Titan Group's structure, the team's dynamics, and the high-octane tone of the series.
