When the woman he loves is in danger, Carthoris follows the footsteps of his heroic parents, John Carter and Dejah, to save her. Carthoris is in love with Thuvia, the princess of Ptarth. Constantly consumed by the thought of her, Carthoris is desperate to proclaim his love. However, Thuvia will not entertain his feelings, as she is betrothed to someone else, and Barsoomian engagements can only be broken through death. Even though his feelings are not reciprocated, Carthoris is still distraught when Thuvia gets kidnapped. Immediately, he rushes to save her. Traveling deep into the undiscovered South, the rescue mission leads to the discovery of an ancient race of Barsoomian, the Lothar. The Lothar are pale-skinned beings with powers that allow them to create illusions purely from their imaginations, yet Thuvia and Carthoris has bigger issues. Back in Ptarth, rumors circulate that Carthoris is guilty of kidnapping Thuvia, and the evidence is stacked high against him. As their two prominent home cities, Ptarth and Helium prepare to battle over this offense, Thuvia and Carthoris must hurry home to stop the war and clear Carthoris' name before it's too late. While Edgar Rice Burroughs' Thuvia, Maid of Mars is the fourth in the Barsoom series, it is the first of the collection to focus on a new generation of characters, Thuvia and Carthoris. With the same level of action, excitement, and imagination of the previous novels, Thuvia, Maid of Mars is a fresh adventure that features new discoveries, unexplored settings, and a relatable romance.
