The Librarian's Inheritance

Competence was her shield. Magic was her legacy. And Millhaven was about to learn that you never mess with a librarian.
At fifty-two, Agnes Calloway valued order, predictability, and the decimal perfection of the Dewey Decimal System. But when her reclusive great-aunt Hester passes away, Agnes inherits the crumbling Calloway Branch Library in the forgotten town of Millhaven-complete with twenty years of unpaid back taxes, structural decay, and an impossible secret.
The library isn't just derelict; it is alive.
Guided by erratic, intense hot flashes that double as a supernatural compass, Agnes uncovers The Calloway Method-a guide to an ancient, epigenetic magic passed down through midlife women. Beneath the dust lies a sentient card catalog and the erased history of Millhaven, a town founded not by industrial barons, but by a suppressed collective of women visionaries.
When Dr. Vance a smooth-talking corporate operative with a trail of burned libraries behind him arrives seeking the town's original 1889 watershed deed, Agnes must step out of the shadows. Armed with an awakened circle of local women, a brilliant teenage volunteer, and a century of meticulously cataloged truth, Agnes must defend her inheritance before her town's past and future is burned to ashes.
