Full Summary

The Robin on the Oak Throne opens with Kierse McKenna, a wisp thief raised unaware of her Fae heritage. She infiltrates the Beltane festival at Versailles to steal an amethyst bracelet from the Queen of the Nymphs. After a narrow escape, she is intercepted by Graves (Grayson Mercer), a master warlock and her estranged lover. Graves proposes a partnership: steal the Cauldron of Dagda from the warlock Estelle Beaumont. Though Kierse distrusts him, she agrees.

During the heist, Estelle reveals the cauldron is missing and that Graves used Kierse as a pawn. Feeling betrayed, Kierse continues alone. Graves later offers to help recover her childhood memories, which have been erased by a powerful spell. He accompanies her into the dangerous Nying Market, where they encounter goblins, a bounty on Graves, and a bookkeeper who confirms Kierse’s wisp nature. They purchase memory-restoring potions.

Back in Dublin, Kierse reunites with her best friend Genesis (Gen), a High Priestess with tarot sight, and learns that her friend Niamh is actually a robin—a spy for Lorcan Flynn, the Oak King. Niamh claims she never reported on Kierse and secretly trained both Kierse and Gen in magic. The group decides to trust Niamh.

Kierse’s memory potions reveal that her parents, Shannon and Adair, sought Graves’s help to hide her wisp powers from the Fae Killer. Graves sent them to rogue Druid Cillian Ryan, who cast a spell on Kierse. Graves believed her parents died, but doubts arise when he finds evidence of a third body. Kierse agrees to help steal the cauldron in exchange for Graves’s aid in recovering her memories.

The team—Kierse, Graves, Gen, Niamh, treasure hunter Laz, and former apprentice Walter—plans to steal the cauldron from the anonymous Curator at Monster Con. Tensions escalate when Lorcan reveals that Kierse is his soulmate. Kierse rejects the bond, but Lorcon forces a handfasting ceremony during the summer solstice, binding her magic to him.

Graves, Gen, and Ethan storm the Oak Throne room. Graves wields the Spear of Lugh and breaks the binding threads, but the ceremony is complete: Lorcan now holds Kierse’s magic, stripping her glamour and abilities. Niamh claims the Oak Throne, becoming head of the Druidic Order. Kierse escapes with Graves.

Back at the brownstone, Kierse learns that the team successfully stole the cauldron. She also discovers that the Curator is Jason, a man she once stabbed and left for dead—who is actually Cillian Ryan, the Druid who siphoned her magic. Kierse confronts him but he escapes.

Graves and the team use the cauldron to break curses and restore magic. Kierse refuses the cauldron’s offer to break the binding in exchange for her humanity; instead, the cauldron grants her full wisp powers through a loophole, restoring her magic without Lorcan’s knowledge. She gains new abilities.

Days later, at Nate and Maura’s wedding, trolls attack under Nova Lee of the Men of Valor. Nate is killed. Kierse realizes a second monster war is beginning. The novel ends with Kierse determined to fight back, her connection to Lorcan still intact but her own powers now free.
