About Moreno and Hart Mysteries
The Moreno and Hart Mysteries series is a collaborative romantic suspense and private-investigation series by Allison Brennan and Laura Griffin. It follows Scarlet Moreno and Krista Hart, two former LAPD officers whose friendship was forged through danger before they opened their own investigation agency in Orange County. The series is shorter than many of Brennan’s solo series, but it has a clear identity: sharp, case-driven suspense with two capable women at the center, balancing professional risk with personal history.
Scarlet Moreno and Krista Hart come into the series with law-enforcement experience, but they are no longer operating inside the LAPD. That change matters. As private investigators, they have more flexibility in the kinds of cases they take, but they also work without the full protection and structure of a police department. Their background gives them instincts, contacts, and investigative discipline, while their new role places them closer to clients, secrets, and danger that can turn personal very quickly.
The first book, Crash and Burn, establishes the basic shape of the partnership. Scarlet and Krista are not presented as amateurs stumbling into crime; they are trained, battle-tested investigators trying to build a new professional life after a violent past. The series premise notes that three years earlier, Scarlet and Krista were nearly killed during a botched sting operation. That history gives the books an immediate sense of trust and trauma. Their partnership is not just a business arrangement. It is rooted in survival, loyalty, and the understanding that both women know what it means when a case goes wrong.
Hit and Run continues the format with danger coming from more than one direction, and it highlights one of the series’ strengths: Brennan and Griffin build suspense through overlapping cases, urgent client problems, and personal complications rather than a single static mystery. Scarlet and Krista’s agency allows the stories to move between missing people, murder accusations, old connections, and threats that do not respect neat professional boundaries. The result is a series that feels brisk and modern, with each installment pushing the investigators into situations where judgment and trust matter as much as evidence.
The novella Frosted is an important part of the series even though it is shorter and sits between the second and third main entries. It brings in Adam Stone, an actor whose connection to Krista adds a lighter but still suspenseful strand to the Moreno and Hart world. The novella format gives Brennan and Griffin room to explore a more focused case and relationship thread without changing the larger direction of the series.
Lost and Found closes the main run by returning to the partnership’s strongest ingredients: private investigation, personal danger, and the kind of case that forces Scarlet and Krista to rely on both their training and each other. Across the series, the appeal is not only in the mystery plots but in the two-lead structure. Scarlet and Krista bring different energies to the page, and the books work because their friendship feels like the foundation beneath the action.
The series is also notable because it joins two authors already known for suspense fiction. Brennan’s crime-thriller pacing and Griffin’s romantic-suspense background fit naturally together, creating a compact series with police-world credibility, emotional stakes, and an accessible private-eye setup. Since the publication list above already handles the exact sequence, the useful takeaway is that Moreno and Hart is best read as a connected partnership series: each story has its own case, but the characters’ shared past and working relationship give the books their continuity.
