The Geomagician by Jennifer Mandula Summary: A Fossil Witch in 1829

Ajax bites Henry’s hand, and both men examine the living animal in disbelief. Buckland subjects Mary to a formal inquisition test with heated golden plates to rule out sorcery.

She passes unmarked. Buckland then proposes his “flood-hibernation theory”: the egg survived dormant in Noachian flood silt rather than being resurrected. He buys the pterodactyl skeleton and the living specimen for 530 pounds and agrees to nominate Mary, telling her to keep the deal from Henry.

Mary, Lucy, Buckland, and Henry sail to London aboard the Unity. During the voyage, Henry reveals that he and Buckland spent a decade building a “compounding machine” called the Loom, which merges magic from many people into manifold reliqs.

In London, Mary lodges with the Bucklands and befriends Catherine Buckland, a gifted illustrator whose career was set aside by marriage, and her eldest daughter Elizabeth.

At Palmanaeus House, Buckland and Henry present Ajax to forty geomagicians and create a sensation. William Conybeare suspects sorcery and reports Mary to the Royal Inquisitors, who arrest her.

During interrogation before the Archbishop of Canterbury and Bishop Price, Mary touches her ammonite reliq and feels living tentacles move inside it. She realizes she is a fossil witch capable of reanimating stone.

Terrified of execution, she commands the ammonite back to stillness and tells the tribunal that Ajax’s waking was an act of God. Buckland supports her with the flood-hibernation theory, and the Archbishop arranges a public cathedral sermon to reconcile science and faith.

After the trial, Henry confronts Mary at Palmanaeus House and lays out his real hypothesis: catastrophes trigger magical surges that create witches, and Mary is one of them. He asks her to test her powers as his secret research assistant.

Mary accepts, having learned that Society bylaws restrict membership to males and that Buckland’s promise could never have been kept. Working from Henry’s flat, she reanimates salamanders, nautiluses, trilobites, and ammonites in room-sized glass tanks.

The creatures begin dying within weeks, returning to stiff corpses. Mary documents their soft tissue anatomy through necroscopies, recording details that fossils never preserve.

Meanwhile, she collaborates with Gideon Mantell and Elias Goldsmild on a paper coining the term “coprolites” for fossilized feces. Lucy, now leading Promethean protests, campaigns for a national blockade of the slicks to force Parliament to raise reliq exchange rates.

At Parliament, a riot breaks out and a sniper’s shot strikes Mary near the heart. Henry saves her life with a single manifold reliq that heals the wound instantly.

Henry then takes Mary and Lucy to his industrial complex, Glasswater Mill. On the manufactory floor, rows of human subjects sit in fluid-filled pods while steam-powered Looms harvest their magic continuously.

Lucy severs her friendship with Mary and vows to destroy the Loom. At the Society’s annual meeting, Henry defeats Buckland for President by 39 votes to 23 and amends the bylaws to allow an exception for Mary.

After a 30-30 tie, Thomas Whaley casts the deciding vote, making Mary Anning the first official female Fellow of the Geomagical Society of London.

Elizabeth Buckland then warns Mary that Lucy plans to destroy the Loom. During Mary’s initiation beneath Palmanaeus House, Conybeare and Sir Oswald Burgess reveal that reliquary serum is made from ground human bone and bitumen, activated by blood-bound sorcery.

Bound by magical blood-oaths, Mary learns the Society has sold twenty-three military manifold reliqs to Lord Knackbull to suppress civil unrest. She rushes to Westminster, where Lucy’s protest is underway and constables detonate a military reliq like a bomb.

Mary rescues the injured Lucy and takes her to Edgar Murray’s house. When Mary confesses everything, Edgar drugs both women with sedative tea.

Mary and Lucy wake bound inside a subterranean cavern beneath Glasswater Mill. Edgar stands before a giant Loom wired to a complete Megalosaurus fossil skeleton and seven live human pods.

Edgar reveals he orchestrated everything, inspired by his late mother’s storm-induced witchery. He intends to use the Megalosaurus as a living reliq to trigger a nationwide earthquake, hoping thousands of survivors will awaken as witches.

Edgar forces Mary’s hand onto the skull. Drawing magic through Ajax, her familiar, she reanimates the towering predator, which breaks its chains and rampages through the mill.

Buckland and Henry arrive. As Edgar tries to direct the earthquake crack toward London, Buckland tackles him into a vat of black serum, and the collapsing ceiling drops the Loom wheel onto both men.

Mary steps into the serum, touches the Megalosaurus, and uses its power to halt the crack before it reaches London. She then commands the bones back to stone.

She finds Buckland crushed and dying. Henry returns with a fossil trilobite, and Mary uses her magic to heal Buckland and the injured Edgar.

To prevent civil war and mass panic, the Archbishop, Bishop Price, Buckland, and Mary agree on a cover-up. They publicly declare the living pterodactyl an elaborate hoax concocted by Buckland and Mary.

Both accept public disgrace and resign from the Society. The Archbishop agrees to negotiate directly with Promethean reformers on reliq wages, while Bishop Price secretly asks Mary to consult for the Inquisition on future cases of fossil magic.

Mary returns to Dorset, closes her town shop, and moves into a quiet cottage on the cliffs of Lyme Regis. Henry visits and returns her correspondence with female scholars such as Marged Davies.

With Ajax on her shoulder, Mary resumes writing scholarly papers, looking out over the sea cliffs where her story began.
