Throne of the Fallen Summary: The Deep Dive

Spoiler Warning: This section reveals major plot points and the ending.

Prince Envy rules the House of Envy, but his court is failing because the Chalice of Memoria has been lost. Without the chalice, his demons cannot purge their memories and fall into a destructive memory fog.

The Unseelie Fae King, Lennox, begins a game that Envy has awaited for decades. Envy’s first clue leads him to a mortal woman capable of painting a hexed throne.

Camilla Antonius runs an art gallery called Wisteria Way in the city of Waverly Green. She secretly creates forgeries to pay off debts and protect her staff after her father’s death.

Lord Philip Vexley blackmails her using her first forgery and her father’s mysterious portal key. Envy, using the name Lord Synton, tracks Camilla down and commissions her to paint the Hexed Throne. She initially refuses because her parents warned her against hexed objects.

Envy rescues Camilla from a ruinous scandal at Vexley’s dinner party. After Camilla kills Lord Garrey in a hedge maze attack, Envy proposes a fake betrothal to protect her reputation.

She accepts in exchange for help retrieving her father’s key and keeping Vexley at bay. As Camilla paints the throne, a hexed creature within it comes to life and steals her magical ability to manifest reality through art. This event reveals to Camilla that Envy is a demon prince.

Camilla travels with Envy into the Underworld to win back her talent and help save his court. They pass through the Sin Corridor, where they are tested by the seven deadly sins.

Their attraction culminates in a night of high-heat intimacy at Envy’s cottage, but Envy insists on a one-night rule to protect himself from emotional attachment.

The quest leads them to House Sloth, where they find the Orb of Golath and summon Golath, the Fear Collector. Golath directs them to the Twin Pillars of Faerie.

Camilla is abducted by a vampire sent by Zarus, the Prince of Malice Isle. Envy fights in a brutal gladiatorial battle against Zarus and four mythical beasts to rescue her.

Zarus dies in the fight, and Blade becomes the new vampire prince. Camilla discovers that Vexley has also entered the game and traded her father’s key to Lennox. She later kills Vexley, who has become a vampire.

At the Twin Pillars, Camilla reveals that she is actually an Unseelie Princess, glamoured since childhood.

They enter the Wild Court, where Lennox reveals his goal was to lure Camilla back and use her locket and the key to open a permanent portal to the mortal world.

In the final battle, Envy summons his hidden emerald wings, tattooed with the Aether Scrolls, to save Camilla from an iron cage.
