One Dark Window Recap

Book facts

Elspeth survives infection and absorbs the Nightmare

Elspeth Spindle catches the fever caused by Blunder's mist when she is nine. Her family sends her to live with her aunt Opal and uncle Tyrn Hawthorn. They conceal her from the King's Physicians, who search for infected children.

After her fever, Elspeth touches a Nightmare Card belonging to Tyrn. Her magic absorbs the Shepherd King's soul from the Card, leaving him inside her mind. She calls him the Nightmare. He can lend her strength and speed, and she can see Providence Cards as colored light, including Cards hidden in other people's clothes.

Eleven years later, her family still does not know what her magic does. On the road home from her twentieth nameday visit to Spindle House, two masked highwaymen question her about Tyrn's Cards. She uses the Nightmare's strength to escape.

At Equinox, Ione is betrothed to Hauth

The Hawthorns attend the Equinox celebration at Stone. Tyrn trades his rare Nightmare Card to the crown, clears his family's debts, and secures a betrothal between his daughter Ione and High Prince Hauth Rowan.

Ione begins using a Maiden Card. It changes her appearance but also suppresses her emotions. Elspeth objects to both the Card and the marriage; Ione refuses to let Elspeth decide for her.

At Stone, Elspeth meets Emory Yew, an infected boy who sees the creature inside her when he touches her. His older brother Ravyn, Captain of the Destriers and the King's nephew, intervenes. Later, Elspeth recognizes Ravyn's ivory-handled dagger: he was one of the highwaymen. Prince Renelm Rowan, called Elm, was the other.

Ravyn recruits Elspeth to find the missing Cards

Ravyn discovers Elspeth's blackened veins and realizes she is infected. Instead of arresting her, he tests her ability to locate Cards. Elspeth demonstrates that she can identify them while blindfolded, but keeps the Nightmare secret.

Ravyn, Elm, Jespyr Yew, the Yew family, and Physician Filick Willow are secretly collecting a Deck. They need one of each of the twelve Card types and an infected person's blood to complete the ritual at Solstice and lift the mist. The King is also collecting a Deck and intends to sacrifice Emory.

Elspeth agrees to help in return for protection and a chance to be cured. She asks Ravyn not to enter her mind with his Nightmare Card. A supposed courtship gives her a reason to move to Castle Yew and work with the group.

The Iron Gate robbery exposes Elspeth to Hauth

The group plans to steal Wayland Pine's Iron Gate Card. Disguised as highwaymen, they ambush his carriage. Hauth, other Destriers, and Elspeth's father Erik are unexpectedly escorting it.

During the fight, Erik gains the advantage over Elm. Elspeth strikes her father with a rock and then uses the Nightmare's power against him. Jespyr loses her protective charm in the struggle and starts following the mist into the forest.

While searching for Ravyn and his spare charm, Elspeth encounters Hauth. He breaks her wrist. She draws on the Nightmare and wounds him before finding Ravyn and helping him reach Jespyr. The group gets the Iron Gate Card and saves Jespyr, but Elspeth's injury gives Hauth a way to identify her later.

Ravyn reveals his infection; Elspeth identifies the Nightmare

At the ruins near Castle Yew, Ravyn shows Elspeth the stone chamber where the group hides its Cards. Infected blood opens the stone. Ravyn tells her he caught the fever at thirteen. Hauth reported him, and the King kept him alive because his resistance to Card magic was useful.

Elspeth and Ravyn kiss in the chamber. She sees the armored, yellow-eyed man from her dreams and realizes the Nightmare is the Shepherd King. He confirms his identity. Each time she uses his power, her degeneration advances and he gains more control of her body.

On Market Day, Elspeth saves an infected child

Hauth stages a public punishment for parents who concealed their infected son. He uses his Scythe Card to make them surrender their charms and walk into the mist.

Elspeth asks Elm to oppose Hauth while she reaches the boy. She attacks Orithe Willow, the head Physician, and takes the child into the mist. She gives him her own charm and sends him after his parents.

Destrier Royce Linden pursues her. Elspeth loses control to the Nightmare and wounds Linden in the neck. Ravyn finds her with yellow eyes and blood on her hands. The child escapes the public punishment, but the search does not locate him afterward.

Emory returns home and warns Elspeth

Emory escapes Stone and reaches Castle Yew, ill from the journey. His degeneration is worsening: he has gaps in his memory and later coughs up blood. He must return to Stone.

That evening, Elspeth tells Ravyn she is degenerating, and they become lovers. She still has not explained the Nightmare to him. The next morning, before Emory leaves, she asks him to look at her again with his magic. He sees that the Nightmare has spread through her and that she has little time left before losing control.

At Spindle House, Hauth uses the Chalice to question them

The group attends Elspeth's half-sisters' nameday celebration at Spindle House and searches for Erik's Well Card. Hauth gives them wine affected by a Chalice Card, forcing them to answer questions truthfully.

He questions Elspeth about her injured wrist. Ravyn uses his Nightmare Card to try to help her and encounters the other presence in her mind. Elspeth becomes violently ill and vomits blood while resisting the Chalice. Ione disengages the Card, and Filick treats Elspeth.

When Elspeth wakes, she allows Ravyn into her mind and tells him that she absorbed the Shepherd King's soul as a child. Later, Erik gives her the Well Card, which came from her mother's family. Filick takes it for safekeeping. Only the Twin Alders is still missing.

Tyrn delivers Elspeth to Hauth and Orithe

While Ravyn is away on patrol, Tyrn tells Elspeth that Opal is waiting upstairs. Instead, he leads her to Hauth. Tyrn has revealed her infection and willingly helped set the trap.

Hauth wants Elspeth to expose Ravyn's activities and help remove him as Captain of the Destriers. He restrains and beats her. Orithe tests her blood and confirms the infection.

Elspeth contacts Ravyn through his Nightmare Card. Knowing further use of the Nightmare's power may cost her control permanently, she asks for his help and makes him promise to protect the Yews.

The Nightmare takes over and bargains for Emory

The Nightmare takes control of Elspeth's body. He kills Orithe and severely injures Hauth. Ravyn arrives too late to prevent the takeover and cannot reach Elspeth's consciousness through his Card.

In the dungeon at Stone, the Nightmare negotiates with King Quercus Rowan. He offers Elspeth's infected blood in Emory's place and says he can retrieve the Twin Alders. He knows where it is because he hid it himself.

The book ends with Elspeth alive but no longer controlling her body. The Deck remains incomplete, Emory still needs a cure, and Ravyn must work with the Nightmare to find the last Card.
