Welcome to The Sunbearer Trials, where teen semidioses compete in a series of challenges with the highest of stakes, in this electric new Mexican-inspired fantasy from Aiden Thomas, the New York Times bestselling author of Cemetery Boys. “Only the most powerful and honorable semidioses get chosen. I’m just a Jade. I’m not a real hero.” As each new decade begins, the Sun’s power must be replenished so that Sol can keep traveling along the sky and keep the evil Obsidian gods at bay. Ten semidioses between the ages of thirteen and eighteen are selected by Sol himself as the most worthy to compete in The Sunbearer Trials. The winner carries light and life to all the temples of Reino del Sol, but the loser has the greatest honor of all―they will be sacrificed to Sol, their body used to fuel the Sun Stones that will protect the people of Reino del Sol for the next ten years. Teo, a 17-year-old Jade semidiós and the trans son of Quetzal, goddess of birds, has never worried about the Trials…or rather, he’s only worried for others. His best friend Niya―daughter of Tierra, the god of earth―is one of the strongest heroes of their generation and is much too likely to be chosen this year. He also can’t help but worry (reluctantly, and under protest) for Aurelio, a powerful Gold semidiós and Teo’s friend-turned-rival who is a shoo-in for the Trials. Teo wouldn’t mind taking Aurelio down a notch or two, but a one-in-ten chance of death is a bit too close for Teo’s taste. But then, for the first time in over a century, Sol chooses a semidiós who isn’t a Gold. In fact, he chooses two: Xio, the 13-year-old child of Mala Suerte, god of bad luck, and…Teo. Now they must compete in five mysterious trials, against opponents who are both more powerful and better trained, for fame, glory, and their own survival.

New York Times\-bestselling author Aiden Thomas returns to the beloved world of The Sunbearer Trials in Celestial Monsters, a heart\-stopping duology finale, in which three young semidioses travel through a dark monster\-infested world, facing down chaotic Obsidian gods, in a quest to save their friends and return the sun to the sky. Teo never thought he could be a Hero. Now, he doesn’t have a choice. The sun is gone, the Obsidian gods have been released from their prison, and chaos and destruction are wreaking havoc on Reino del Sol. All because Teo refused to sacrifice a fellow semidiós during the Sunbearer Trials. With the world plunged into perpetual night, Teo, his crush Aurelio, and his best friend Niya must journey to the dark wilderness of Los Restos, battling vicious monsters while dealing with guilt, trauma, and a (very distracting) burgeoning romance between Teo and Aurelio. Determined to rescue the captured semidioses and retrieve the Sol Stone, the trio races against the clock to return Sol and their protective light. With it, order can be restored. The future of the whole world is in their hands.
