The Book in Brief
Astok of Dusar attacks Thuvia in her father's garden, and Carthoris drives him off. Carthoris loves Thuvia but learns that she is promised to Kulan Tith. Astok then plants the spy Vas Kor in Carthoris's household and uses a duplicate of Carthoris's craft to abduct Thuvia and frame Helium.
Carthoris pursues the kidnappers, crashes near ancient Lothar, and finds Thuvia after she has fallen among green warriors. Phantom bowmen destroy the attackers, and the pair enter a city divided between the rival illusionists Tario and Jav. Their powers create armies that can kill despite having no ordinary bodies.
Carthoris, Thuvia, and the increasingly real bowman Kar Komak escape Lothar through battles with Komal, green men, and white apes. Astok recaptures Thuvia and orders her death to prevent discovery, while Carthoris disguises himself as the panthan Turjun and infiltrates Dusar's forces.
Carthoris rescues Thuvia and carries her toward Ptarth, but stops to save Kulan Tith from a green horde. Kar Komak summons a final army, and Kulan survives to hear Thuvia confess her love for Carthoris. Recognizing their honor, he releases her from the betrothal.

Chapter-by-Chapter Summary
The headings and sequence follow the complete 14-chapter Project Gutenberg edition.
Chapter I: Carthoris and Thuvia
Astok assaults Thuvia in the gardens of Ptarth, but Carthoris intervenes and humiliates him. Carthoris then learns that Thuvia is already promised to Kulan Tith and leaves without confessing his love.
Chapter II: Slavery
Astok's agent Vas Kor enters Carthoris's household under the identity of a purchased slave. The infiltration gives Dusar access to the prince's plans and technology.
Chapter III: Treachery
Thuvia is abducted in a craft made to implicate Carthoris, and war threatens among Helium, Ptarth, and Kaol. Carthoris follows the trail, recognizes Thuvia aboard the fleeing vessel, and is drawn toward the frame-up.
Chapter IV: A Green Man’s Captive
Astok's men leave Thuvia exposed after disguising their role, and green warriors seize her. Carthoris searches nearby ruins and descends through a dark tunnel toward Lothar.
Chapter V: The Fair Race
Carthoris reaches Thuvia and watches an immense force of phantom bowmen destroy the green warriors before vanishing with their own dead. The mystery leads the pair into the inhabited ancient city.
Chapter VI: The Jeddak of Lothar
Jav explains that Lotharians project warriors and banths through concentrated thought, then presents the visitors to Tario. The ruler's suspicion and the city's rivalry make their supposed refuge dangerous.
Chapter VII: The Phantom Bowmen
Tario turns against Carthoris while Jav's loyalty proves equally unstable. Carthoris rejects the logic of fighting imagined enemies and forces his way out to protect Thuvia.
Chapter VIII: The Hall of Doom
Tario tries to frighten and possess Thuvia, but Carthoris returns and confronts him. Tario drops Carthoris, Thuvia, and Jav through a trap into the chamber beneath the Hall of Doom.
Chapter IX: The Battle in the Plain
The captives evade Komal and escape the pit while Jav calls up forces against Tario. Once outside, Jav attacks Thuvia, and the growl of a pursuing banth interrupts him.
Chapter X: Kar Komak, the Bowman
Thuvia's belief gives the bowman Kar Komak and the banth Komal physical force. Carthoris, Thuvia, and their new ally head toward Aaanthor and meet green warriors and arriving Dusarians in battle.
Chapter XI: Green Men and White Apes
Carthoris is stunned and chained by green men, but white apes break the captors' hold. He reunites with Kar Komak, escapes the dead city, and meets Hal Vas, who unknowingly offers him service in Dusar's cause.
Chapter XII: To Save Dusar
Komal saves Thuvia from Jav, but Astok's forces capture her and decide she must die before her presence exposes Dusar's crime. Astok races to locate Vas Kor as the wider war closes in.
Chapter XIII: Turjun, the Panthan
Calling himself Turjun, Carthoris joins Hal Vas's command and uses the enemy appointment to pursue Vas Kor and Astok. He follows their flier into the palace corridors where Thuvia is held.
Chapter XIV: Kulan Tith’s Sacrifice
Carthoris rescues Thuvia and later risks both freedom and love to save Kulan Tith from a green horde. Kar Komak's projected bowmen rout the attackers, and Kulan, hearing Thuvia's confession, releases her to marry Carthoris.
Ending Explained
Why does Carthoris save Kulan Tith?: He places Thuvia's safety and honorable conduct above his private hope that a rival's death would free her.
What happens to Kar Komak?: He leads his summoned bowmen after the retreating green warriors and disappears from the lovers' immediate story, leaving them free of Lothar's strange politics.
Why does Kulan release Thuvia?: He recognizes that she loves Carthoris, that she has not acted dishonorably, and that Carthoris risked his life to save him.
How is the political crisis resolved?: Thuvia's recovery and Carthoris's conduct disprove Helium's responsibility for the kidnapping, removing the lie on which Astok built the war.
Themes and Motifs

Inherited heroism: Carthoris acts under John Carter's reputation but must prove his own judgment.
Courage and cowardice: The novel contrasts physical valor with rulers who hide behind projections and deception.
