Quick Facts

Short Summary

Signa Farrow is an immortal young woman who can see the dead after ingesting belladonna. Orphaned as an infant after a mysterious poisoning killed her family, Signa has spent years moving between guardians, each of whom died prematurely. She believes Death himself is responsible. When a distant relative summons her to Thorn Grove, Signa discovers her cousin Blythe is dying from the same illness that killed Blythe’s mother, Lillian. Convinced that Death is pursuing the family, Signa resolves to save Blythe. But as she investigates, she learns the poison is belladonna—and that someone is deliberately administering it. With the help of the mysterious stable hand Sylas Thorly, who may be more than he appears, Signa uncovers a web of family secrets, betrayal, and murder. She must embrace her own connection to Death and decide how far she will go to protect those she loves.

Full Summary

Belladonna opens with a prologue at Foxglove Manor, where two-month-old Signa survives a poisoned wine that kills everyone else, including her mother. Death, fascinated by the infant who can see him and who shows him visions of her future, spares her.

Seventeen years later, Signa lives with her aunt Magda, who fears her as a “demon-child.” Using belladonna berries to summon Death, Signa confronts him, blaming him for the loss of every guardian. When Death appears, Signa accidentally kills Magda—her touch becomes lethal only when she is under belladonna’s influence, in a liminal state between life and death. Death promises to return in two days.

A carriage arrives from Elijah Hawthorne, husband of Lillian (who was Signa’s mother’s friend). The stern stable hand Sylas Thorly escorts Signa to Thorn Grove. On the train, Sylas reveals Lillian died from a mysterious illness and her daughter Blythe now suffers the same.

At Thorn Grove, Signa meets the cold cousin Percy, the kind governess Marjorie, and attends a chaotic ball where Elijah’s grief manifests as perpetual parties. Signa discovers Lillian’s portrait in an upper room and finds Blythe severely ill. Lillian’s ghost appears, her mouth damaged, and guides Signa to uncover the truth.

Signa forces her way into Lillian’s hidden garden with Sylas’s help. There, she eats more belladonna to enter the veil and speak with Death. Death reveals that Signa has inherent reaper abilities—she is not merely using his powers. He explains that he spared Blythe, who was meant to die, because Signa’s killing of Magda upset the life-death balance. Death admits he orchestrated Signa’s arrival at Thorn Grove.

With Death’s help, Signa summons Lillian’s spirit, who communicates that she was poisoned. Signa resolves to find the killer. She forms an alliance with Sylas, bribing him with a position in her future household. Together they search for clues, including a hidden letter in Elijah’s office at Grey’s (the family business). Signa grows closer to both Sylas and Death, who begins training her in her reaper powers.

Signa discovers Blythe’s “medicine” is laced with belladonna. She and Percy obtain a Calabar bean, the antidote, from an apothecary. Signa tests it on herself before giving it to Blythe, who begins to recover. But the poisoner strikes again at the Christmas masquerade ball, poisoning Percy. Signa uses the last dose of antidote to save him.

Investigating further, Signa uses belladonna to become invisible and searches the house. In Marjorie’s room, she finds a journal revealing Marjorie’s love for Elijah and hatred for Lillian. More damningly, Marjorie’s fingertips are stained the color of belladonna. Signa confronts her; Elijah banishes Marjorie from Thorn Grove. But Blythe is dying again, and Signa has no antidote left. She bargains with Death, offering a life in exchange for Blythe’s. Death grants it, and Blythe stabilizes. Signa later learns the price was a stranger’s remaining ten years.

Death takes Signa to the afterlife bridge, where she accepts her reaper nature. They become intimate in the forest, and she chooses him over a normal life. Elijah then reveals that Percy is his and Marjorie’s biological son, explaining Marjorie’s presence. But during the search for the poisoner, Percy confesses everything in a confrontation at the burning garden: he poisoned Marjorie’s tea, his mother Lillian instead drank it, and he continued the poison to hasten her death. He also poisoned Blythe. He set the garden fire and poisoned himself at the ball to force Signa to use the last antidote, manipulating events. In that moment, Sylas reveals he is Death himself; Gundry is a hellhound. Signa embraces her powers, traps Percy with dead bramble, and orders Gundry to devour him.

Lillian’s spirit appears healed and says goodbye to Elijah. Percy’s remaining years are given to Blythe. Signa and Death (in his Sylas form) address his deception, and she accepts his reasoning. Blythe recovers fully, and the household finds peace. Death warns that he will be less able to visit now that the crisis is over, urging Signa to live fully. She refuses to accept separation, and they vow to find stolen time together.

In the epilogue, at a celebration ball for a new business partnership, Duke Julius Wakefield drinks poisoned champagne and dies. Death appears, and a new golden-eyed figure named Fate arrives, revealing the murder and telling Signa she must solve another mystery.
