Circle of Days Summary: The Deep Dive
SPOILER WARNING: This section recounts the complete plot, including the ending.
In the year 2500 B.C.E., the Great Plain of prehistoric Britain is a vast, untamed landscape divided into three distinct human societies: the herders, the farmers, and the woodlanders.
The herders reside in cooperative villages like Riverbend, sharing resources and cattle collectively under the gentle, consensus-driven guidance of their elders. The farmers, centered in Farmplace, practice individual agriculture and live in a rigid, male-dominated society where women are treated as property.
The woodlanders are nomadic hunter-gatherers living in West Wood, maintaining a harmonious, loose social structure without central leaders.
At the geographic and spiritual center of these communities sits the Monument, a sacred wooden circle where all tribes gather quarterly to trade and honor the sun.
The plot is set in motion by Seft, a young flint miner who suffers under the brutal hands of his father, Cog, and thuggish older brothers, Olf and Cam.
Following a romantic meeting with Neen at the Spring Rite, Seft rebels during a trading trip, physically fighting his family and fleeing into the wilderness.
He finds refuge working in Wun’s pit, demonstrating a rare gift for innovative carpentry. When Olf attempts to kidnap him back, Seft defends himself, slashing and half-blinding Olf with a flint knife.
Meanwhile, Neen’s younger sister, Joia, is caught spying on the priestesses’ midsummer sunrise ceremony.
Instead of being punished, she is mentored by High Priestess Soo. Joia learns their sacred mathematical secrets for tracking the 365.25-day year and decides to dedicate her life to the sisterhood.
Peace on the plain shatters when the greedy farmer leader, Troon, plows up the Break, a vital corridor of herding land providing cattle access to South River.
After negotiation fails, herder elder Scagga retaliates by burning the farmers’ crops with birch tar.
The farmers strike back, burning the wooden Monument to the ground.
Joia and Seft propose an unprecedented, monumental project: rebuilding the sacred circle entirely in stone using the massive sarsen stones from Stony Valley.
Ten years of a devastating drought ensue, straining the communities to their breaking points.
Desperation sparks when a herder named Robbo murders a priestess named Inka during an argument over slaughtering a heifer. Han, Neen and Joia’s younger brother, witnesses the crime.
Meanwhile, Han and farmer girl Pia are deeply in love. Following the death of Pia’s father Alno, Troon cruelly forces Pia’s widowed mother Yana to partner with his abusive young son Stam. Desperate to escape, Pia and Han flee to the Northwest Hills, where Pia gives birth to a boy, Olin.
Stam tracks them down, murders Han and Fell (a woodlander friend) with arrows, and drags Pia back. Bez, Fell’s brother, exacts bloody retribution by kidnapping and executing Stam by fire.
When the herders’ thirsty cattle stampede through the Break to reach water, destroying farmer crops and killing a farmer named Mo, war is declared.
A new clearing is built through West Wood, but Scagga’s attempt to burn the brush accidentally consumes the woodlanders’ entire home.
Left destitute, the woodlanders begin raiding farmer stores, leading the farmers to commit a horrific massacre of woodlander women, children, and elderly.
Woodlander survivors burn down the temporary wooden Monument and attack Riverbend before being repelled.
Determined to reunite the ebbing collective spirit of the herders, Joia (now High Priestess) organizes a monumental mission to transport nine massive sarsen stones using a wooden sled designed by Seft.
Troon and his Young Dogs attempt to sabotage the mission, murdering herders Dab and Revo.
Troon prepares his army to attack the Monument on Midsummer Day to stop the herders’ dominance.
To prevent a bloodbath, Joia and Zad orchestrate a massive stampede of the cattle herd against the advancing farmers, decimating the attackers. Joia executes the severely wounded Troon by driving a bradawl into his throat.
Following the battle, Duff is chosen as the new Big Man of Farmplace, liberating the women and establishing gender equality and property ownership.
Pia and Duff raise Han’s son Olin. Fifteen midsummers later, the Monument stands fully completed with thirty stone uprights and thirty crossbars.
Thousands gather to celebrate, and the aging elder Ani is carried to the circle by Joia, Neen, Seft, and Ilian to witness the midsummer sunrise shining through the majestic triliths, marking a legacy of survival and cooperation.
