Binge or Drip? The Serial Reading Argument No One Actually Wins

There are two kinds of readers in the world.
The kind who says, “Just one more chapter,” and resurfaces hours later dehydrated and emotionally compromised.
And the kind who prefers the slow burn—one episode a week, time to speculate, time to argue, time to savor.

The internet insists one of these is correct.

They’re wrong.

This isn’t a format war. It’s a control issue—and Credible Threat is about to give both camps exactly what they want.

A No-Spoiler Update on Fall From Grace

Thomas Billings is back.
Well… almost.

Mark filed a no-spoiler update on Fall From Grace, the second Thomas Billings thriller, and it contains precisely zero useful intel — which is exactly the point. What we do know: the book exists, words are happening, and coffee is disappearing at an alarming rate. Thomas is stubborn, Grace is complicated, and someone (possibly several someones) is making catastrophically poor choices.

In other words: the thriller is doing what thrillers do best.
And Mark will start spilling details only when the finish line is in sight.

Until then… someone, somewhere, is about to regret something deeply.

Release Day! I’ve Joined the Uncollected Anthology—And Sister Jacobine Has Opinions

Mark Posey joins the long-running Uncollected Anthology with Bones of the Priory, a dark, atmospheric Sister Jacobine story in the new Monster Hunters issue. Jacobine returns to the ruins of her childhood nunnery expecting quiet reflection—but what she finds is her immortal sister Margaret, and a confrontation centuries in the making.

Back in the Trenches: Fall From Grace Begins

Back in the trenches: I’ve started writing Fall From Grace, Book 2 in the Thomas Billings thrillers. Thomas and Grace head to London for an audience with the Queen—then get yanked into Establishment crosshairs. Expect chases, betrayals, and the kind of moral gray that leaves even “good guys” guessing.

The Hazeldean Artisan Market—Wait, When?

Mark reflects on the strange physics of author life—writing about the Hazeldean Artisan Market before it happens, even though you’re reading about it after the fact. Between the smell of coffee, glitter-covered tables, and fellow creatives, he celebrates the timeless joy of connecting with readers and fellow artisans (and maybe bending the space-time continuum just a little).

Confessions of a Sadistic Author

Why do authors put their characters through hell? Because without conflict, there’s no story. In Confessions of a Sadistic Author, Mark explains why Jacobine, Billings, and the rest of his cast are constantly battered and bruised — and why their scars make them unforgettable.

So, You’ve Spoken (and I’m Listening… Mostly)

The votes are in, the ballots counted, and my writing schedule is now set—thanks to all of you. Fall From Grace is up first (yes, Thomas Billings is about to get shoved off an emotional cliff). Next comes Sister Jacobine #7—because apparently six books of bullets, assassins, and bad coffee weren’t enough for you. And finally, Credible Threat, Season 2 rounds things out. I’ll admit, I briefly considered ignoring the results and writing a cookbook instead—“101 Ways to Kill a Man With Kitchen Utensils” still has a nice ring to it—but you spoke, and I’m listening. Mostly.

Jacobine vs. Billings: Who’s More Fun to Torture?

One of the perks of writing thrillers is getting to torture characters. Jacobine makes me work harder—she’s deadly, clever, and never blinks. Billings, though, is convinced he’s in control…until the floor drops. Who’s more fun to torment: the nun with a gun, or the cocky spook?

Help Me Decide What to Write Next

Mark’s got three thrilling projects fighting for attention in his brain—another Jacobine adventure, a high-octane Billings sequel, or a brand-new season of Credible Threat. He’s throwing the decision to readers: which story should he dive into next?
