The wards are humming. The oak is restless. And beneath Mossmere’s oldest tree, something is waking up.

Autumn has come to Mossmere, and apothecary witch Mira Thorne is preparing for the Harvest Illumination, the village’s most cherished festival. But when heavy rains expose a hollow beneath the great oak, Mira discovers a sealed spellbook bearing the village’s founding sigil and something she has never seen before: unfamiliar binding lines threaded through the familiar magic.

Opening the book sends a tremor through the ward lattice. Lanterns flare green. Warming charms freeze. And the deeper Mira reads, the more she uncovers a truth the founders buried along with the book: a fragment of wild magic, trapped beneath the oak for centuries, leaking through a containment shell that is slowly coming undone.

With the festival days away and the village divided between fear and trust, Mira must decipher the founders’ dual-ink annotations, confront an elder’s decades-long secret, and design a ritual that could transform Mossmere’s relationship with the wildness at its heart, or shatter the wards that keep it safe.

The Spell Beneath the Harvest Oak is the second book in The Mossmere Coven Chronicles; a cozy witch fantasy for readers who love practical magic, found-family warmth, and mysteries where the real tension lies in secrets, trust, and the courage to let go of what you’ve always feared.

Perfect for fans of: T.J. Klune, Travis Baldree, and Sangu Mandanna.

Can be read as a standalone.
