What’s On My Desk This Summer

Writers rarely work on just one book at a time. While readers see the finished novel, there’s often an entire queue of stories in progress behind it—drafts, edits, serials, and ideas waiting for their turn. Here’s a look at what’s currently occupying my writing desk this summer, from new thriller adventures to ongoing serial fiction and the next novel waiting in the wings.

The Joy of Not Turning to the Last Page

What if waiting for the next chapter isn’t a flaw in storytelling, but one of its greatest pleasures?

In a world built around instant gratification, serial fiction offers something different: anticipation. Readers spend time with characters, speculate about what comes next, and let stories become part of the rhythm of their week. As The Summer Garden continues and Credible Threat: Season One joins it, Mark Posey reflects on why the joy of not turning to the last page may be more valuable than ever.

Bones of the Priory Is Out Today

A letter from someone who should have been dead for centuries draws Sister Jacobine back to the ruins of Amesbury Priory and the place where her long, impossible life began. Bones of the Priory started as a contribution to a monster hunter anthology, but it quickly became something more personal—a return to one of my favourite characters and the secrets she has spent five hundred years trying to leave behind.

Why Buying Direct Matters More Than You Think

Readers often wonder whether buying books directly from an author’s website really makes a difference. The answer is simple: it does. Direct sales help fund editing, cover design, and future books, while creating a closer connection between readers and the authors whose stories they enjoy.

Something New is Growing

A retired widower. A community garden. A cast of unforgettable neighbours. While Fall From Grace continues to take shape, Mark Posey has also been nurturing a very different story. The Summer Garden is a warm, character-driven serial about grief, friendship, second chances, and the surprising ways people keep growing long after they think life’s most important seasons have passed.

Sorry About the Lost Sleep

Ever sit down with a book thinking you’ll read just one chapter before bed… and suddenly it’s 2:03 a.m.? Mark Posey confesses why those “just one more chapter” moments are sometimes a little bit deliberate—and why writers secretly love hearing about them.

I Forgot I Wrote This Book

I forgot to bring my own time-travel thriller to the market. Not sold out—forgot to order it. Which is impressive, considering I wrote it. If you like high-stakes time travel, moral consequences, and science that actually matters, this is your reminder.

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.

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.
