Out Now

A deserted small-town main street under a green storm sky, crows gathered on the power lines
The Z-Strain cover: the title in huge white block letters over a green storm sky, a family silhouetted on a cracked road walking toward a ruined city
Z-Strain — out now

“The outbreak started in a small town.”

Z-Strain

The world ended. We didn't.

A zombie novella · Horror

A fast, brutal small-town zombie novella. One ordinary town, one very bad outbreak, and the thin line between the neighbors you wave at and the things you barricade the door against. In this town, the monsters know your name. It does not waste a page — neither do the dead.

The Bound Consort

The Veiled Academy · Book One — by A.S. · dark paranormal romance

She hacked the wrong server. Now it’s living in her head.

Rowan Hayes has three rules for staying alive as a hacker. She broke all three before midnight. An itch she couldn’t explain drew her to Sinclair Global — a corporation too clean, run by a CEO no one has ever seen. She went looking for the lie buried in their servers. She found a sub-basement that shouldn’t exist, a name that shouldn’t matter, and teeth. Now she’s Blood-Marked, bound by a forbidden Blood-Link to Dorian Sinclair himself: ancient, untouchable, and suddenly living inside her head. The Sanguine Council calls their bond heresy. The wards of Nightshade Academy call her something else. Little star. They’ve been waiting.

“When the unwilling are bound, twin stars shall rise — one born of the old blood, one marked by it. The thrones of the old shall crack beneath their light. One star to shatter the order, one to save it — or both to burn the sky together.” — the Twin Stars prophecy
