website crime scene tape and body.jpg

Dive into Christian suspense, small-town mysteries, clean romance, and forensics galore. Police procedurals and behavioral science. Let's not forget science fiction & speculative thrillers, and genetic engineering.

Explore the Whiskey River series and standalone novels, and discover stories grounded in forensic realism, humor, and faith.

Catherine Cade is chaos in lip gloss—and she has a problem. Several, actually. An amnesiac, identity thief, and a sudden born-again amateur sleuth, she’s discovering that uncovering small-town secrets might involve more running than seasoning—and an alarming number of baked goods.​

 Cade's convinced the small-town police department is up to something shady when a homicide detective shows up for a death certificate--super shady. So if she can’t remember her past, she can at least rewrite her future—preferably without handcuffs.

Homicide detective Rick Calhoun has problems of his own. His new murder suspect keeps breaking into the evidence locker. Catherine Cade. She’s tangled in a high-profile investigation, knows far too much, and has a habit of baking her way into places she definitely shouldn’t. He's one migraine away from retirement.

 

Did she do it? Or is someone staging the perfect sugar-coated setup?

Catherine needs a plan: hide, run, or charm Rick with enough cinnamon rolls to buy leniency. Rick needs a plan too—figure out whether to arrest her, work with her … or somehow keep her close long enough to see what she’s really hiding--or what she knows.

When the case explodes and bullets start flying, they’ll have to decide what they’re willing to sacrifice--their safety, their secrets, or the unexpected spark igniting between them.

In Whiskey River, falling in love can be a crime all its own.

  • "Funny, tearjerker, inspirational. Cade is an "unreliable narrator" giving her perspective as dysfunctional as it is funny (well, at least in my mind). The ending has a twist, so have your cry and finish the book or you'll lose out on the finale."

Jack McCloud is a medical examiner with a simple plan. Maybe hire a lab tech who doesn’t want to assassinate him.

 

Enter Mercedes Hall, baby in arms, toddler in tow, and suddenly his life of grumptitude is officially over. Jonah’s oatmeal-covered hands meet Jack’s face, and for the first time … he laughs on the inside. Heaven forbid he laugh out loud.

 

The murders are bizarre. The clues are stranger. And the forensics? Mind-bending. Only Mercedes’s scientific persistence—and a little bit of silk—can unravel the truth.

 

As the body count rises and their lives—and little Jonah—hang in the balance, Jack and Mercedes have to navigate chaos, crime, and their growing feelings. The danger is real, the humor is relentless, and the love that sneaks in might be the only thing keeping them alive.

 

Silk & Slippers is Christian romantic suspense with snark, science, and twisted suspense—where faith, fortitude, and chaos collide.

Shanghai Road 

shanghai cover with christlit logo.jpg

Shanghaiing is dead. Trafficking just changed its weapon.

Allie Espinoza wants one thing—a real shot at becoming Whiskey River’s go-to private investigator. Instead, her first case drags her into a messy, off-the-books hunt for evidence of fraud … and straight into a criminal operation far more dangerous than she expected.

When she runs, she doesn’t get far. Deputy Ben Johnson catches her, unmasks her, and hauls her into the Whiskey River Police Department. They’re short-staffed, drowning in leads, and desperate enough to hire her as a consultant.

The deeper Allie and the PD dig, the more twisted the case becomes. Trafficking, hidden networks, and a web of lies stretch across town, and someone out there is willing to kill to keep it buried.

Allie must navigate the edges of the law, fend off a cranky police chief who’d love to throw her out, and survive unknown enemies closing in fast. As she and Ben confront their own shadows, they realize one of them may be the next target.

A rule-bending PI and a straight-arrow deputy stumble into a trafficking case that tests their faith, shreds their patience, sparks an inconvenient attraction, and proves God absolutely has a sense of humor … even when the evidence doesn’t.

Science Fiction Standalone

Rules of Engagement dives headfirst into a terrifyingly plausible scenario: a genetically modified Ebola virus sweeping the globe with surgical precision. As chaos erupts, Army Ranger Scott Walker is assigned to protect—and work with—sharp-tongued microbiologist Cheyenne Keyes to track the source and stop a diabolical plan before it’s too late.

Real science. Real stakes. Real danger.

Viral splicing is real—just look at modern medicine and the history of banned bioweapons.

Scientists and politicians have long believed they can control such weapons, despite centuries of proof to the contrary.

The military? They're often on the front lines—whether promoting, preventing, or cleaning up the aftermath.

And when soldiers are assigned to protect scientists, professional lines may blur... but where it leads is anyone’s guess.

 

From weaponized viruses and covert military ops to political deception and fragile alliances, this high-octane sci-fi, medical/military thriller explores just how far mankind will go to control the uncontrollable.

Can a soldier and a scientist save the world—and each other?

A cautionary tale of what's happened through the centuries.
