Rebecca Deel’s romantic suspense is best understood as one shared world with four main branches. The practical reading question is not “Which series is separate?” so much as “How much crossover do you want?” Otter Creek starts the universe, Fortress Security expands it, Maple Valley runs alongside that world, and Fortress Security: Artemis is the newest extension.

For most readers, the best entry is Otter Creek #1, Witness. If you want the cleanest long-form experience, move from Otter Creek to Fortress Security, then Maple Valley, and finish with Fortress Security: Artemis.

The fast answer
- Best place to start: Witness
- Best simple reading path: Otter Creek → Fortress Security → Maple Valley → Fortress Security: Artemis
- Why this works: it keeps introductions early, avoids dropping into the middle of an already-established team network, and saves the newest spin-off for last.
How Rebecca Deel’s books connect
Rebecca Deel’s four confirmed series are all tied to the same larger world. Goodreads’ shared-universe series listing notes that Otter Creek and Fortress Security cross over as they progress, while Maple Valley and Fortress Security: Artemis extend that same network later.
That means there are two valid ways to read her books:
- Simple route: read each series in order, one branch at a time.
- Completionist route: follow the interwoven shared-universe sequence from the author’s ecosystem and crossover listings.
For most new readers, the simple route is the better recommendation because each book is still built to work as its own romantic-suspense story.
Recommended reading order
- Otter Creek
- Fortress Security
- Maple Valley
- Fortress Security: Artemis
This is not the tightest crossover-by-crossover sequence, but it is the clearest one for a first read. The later books land better when you already know the earlier investigators, operatives, and protection teams.
Otter Creek books in order
This is the foundation line. If you want to meet Deel’s world before the security-firm side takes over, begin here.
- Witness (2015): A burglary-and-murder case opens the universe with a small-town investigation that quickly turns personal and dangerous.
- Hidden Target (2015): A heroine determined not to become a killer’s next victim is forced into a tighter game of pursuit and survival.
- Written in Blood (2015): A newspaper editor turns herself into bait after a friend’s murder, giving the series an even sharper cat-and-mouse edge.
- Fatal Legacy (2015): A cluster of deaths turns into a race against a killer, pushing the series toward bigger emotional and investigative stakes.
- Payback (2015): A past mission comes roaring back, making old choices and unfinished danger central to the story.
- Best Served Cold (2015): A U.S. Marshal story that shifts the branch toward heavier law-enforcement pressure and higher-threat protection work.
- In Plain Sight (2016): A life-changing diagnosis and a fresh threat collide, making vulnerability and concealment part of the suspense.
- Retribution (2016): Revenge and unfinished justice drive this installment, with the series leaning harder into consequences from the past.
- On the Edge (2017): An ER nurse who knows crisis too well is pulled into danger that demands both nerve and trust.
- Vendetta (2017): A choice made years earlier comes due, giving the book a strong past-meets-present structure.
- No Regrets (2018): A routine errand erupts into violence, dropping the heroine into the orbit of an elite rescue team.
- Under Fire (2018): The pressure rises with direct threat and active danger, making this one feel especially urgent inside the series run.
- Relentless (2018): Persistence becomes the point here, with the story pressing forward through sustained danger rather than a single isolated incident.
- Don’t Let Go (2019): The emotional side of the series comes to the front as danger tests loyalty, resilience, and attachment.
- Caught in the Crossfire (2019): The branch closes on a title that signals exactly what it delivers: converging threats, divided pressure, and a heroine caught in the middle.
Fortress Security books in order
Fortress Security is the biggest branch and the center of Deel’s action-heavy shared world. Once you start here, reading in order becomes more rewarding because the firm, its operatives, and its internal relationships keep accumulating weight.
- Midnight Escape (2015): A rescue mission launches the series with private-investigation energy before Fortress fully becomes the center of the universe.
- Midnight Reckoning (2015): Family crime, moral contrast, and looming threat give the second book a stronger reckoning theme than the opener.
- Midnight Rendezvous (2015): Past and present collide, pushing the series toward more layered suspense and relationship fallout.
- Wheels of Justice (2016): Personal loss and vulnerability meet protective force, broadening the kind of cases Fortress handles.
- Deadly Game (2017): A desperate plea for help turns into a higher-stakes operation and helps the series feel more team-driven.
- Resurgence (2017): Hardship and comeback energy define this installment, with the series leaning into endurance under pressure.
- Obsession (2017): A missing mother and a volatile threat sharpen the emotional tension while reinforcing Fortress’s protective role.
- Shadow Guardian (2018): Diplomatic danger and elite protection work move the branch into a more overtly tactical phase.
- Shadow Rescue (2018): Rescue urgency and team capability take center stage, making this one feel especially tied to the firm’s mission.
- Shadow Undercover (2019): The undercover angle adds deception and layered risk to a series already built on trust under fire.
- Shadow Redemption (2019): Redemption becomes the hinge here, giving the suspense a stronger emotional payoff.
- SEAL’s Promise (2020): The military background that has always fed the series becomes even more explicit in this team-centered entry.
- SEAL’s Resolve (2020): Determination and follow-through drive the story, keeping the firm’s world cohesive as the cast expands.
- Final Cut (2021): This installment brings a sharper sense of confrontation and closure, with pressure tightening around the central threat.
- Collateral Damage (2022): A kidnapping attempt and missing friend widen the danger, showing how even indirect blows can reshape the mission.
- Fallout (2023): The aftermath matters as much as the attack itself, giving this book a strong consequences-first momentum.
- Leverage (2023): Power, pressure, and strategic manipulation define the suspense engine here.
- Death Wish (2024): The title signals the tone: this is a darker, more openly perilous installment in the later Fortress run.
- Last Chance (2024): A rerouted mission and hostage crisis bring the main series to a fittingly high-pressure late-stage entry.
Maple Valley books in order
Maple Valley sits inside the same broader world but feels a little more local in structure. It is a good next step after Fortress because it gives you connected-world continuity without asking you to relearn how Deel writes suspense.
- Security Breach (2020): A woman on the run turns to the most dangerous man she knows, opening the series with witness-protection tension and personal history.
- Marine’s Mission (2020): A terrorist threat pulls a heroine and a Marine into a mission where national security and personal loyalty become inseparable.
- Conspiracy (2021): An ambushed police chief refuses to back down, giving this book a tougher procedural spine than the earlier entries.
- Buried Secrets (2022): Hidden history and delayed consequences drive the suspense, making the title’s promise literal and emotional at once.
- Deadly Trap (2023): A grieving woman trying to build a quieter life becomes a target, turning recovery into the setup for fresh danger.
Fortress Security: Artemis books in order
Artemis is the newest branch and the easiest one to save for last. It works best once Fortress already feels familiar.
- Covert Mission (2024): The spin-off begins with assassination-prevention stakes and a covert-protection setup that clearly grows from Fortress DNA.
- Montana Manhunt (2025): A return home and a serial-killer pursuit give this entry a justice-driven hunt structure.
- Fatal Intent (2025): Ghosts from the past push the team into a confrontation shaped by memory, history, and active threat.
- Storm Warning (2025): The title suggests looming escalation, and the series continues to operate in a danger-first, mission-heavy mode.
- Day of Reckoning (2026): The newest confirmed Artemis novel pushes toward buried secrets, exposed truths, and the cost of surviving betrayal.
Should you read the shared universe in strict crossover order?
Only if you are the kind of reader who likes catching every entrance exactly when it happens. The shared-universe listing confirms that Otter Creek and Fortress Security interleave as the two series grow, but each individual book is still designed to stand on its own.
That is why the safer recommendation remains simple: read the books by series, in order, and move forward through the branches as the world expands.
Where new readers should begin
Pick your start based on what you want most:
- Start with Witness if you want the true beginning of the world.
- Start with Midnight Escape if you mainly want elite-security action.
- Start with Security Breach if you want a later entry point without committing to the biggest series immediately.
- Do not start with Artemis unless you already know you are comfortable entering late.
Latest release status
As of April 16, 2026, the newest widely listed Rebecca Deel release is Day of Reckoning, identified as Fortress Security: Artemis Book 5. That makes Artemis the current endpoint of her confirmed connected romantic-suspense catalog.
