Description: The Jazz Age is in full swing, but Casiopea Tun is too busy cleaning the floors of her wealthy grandfather’s house to listen to any fast tunes. Nevertheless, she dreams of a life far from her dusty small town in southern Mexico. A life she can call her own.

Yet this new life seems as distant as the stars, until the day she finds a curious wooden box in her grandfather’s room. She opens it—and accidentally frees the spirit of the Mayan god of death, who requests her help in recovering his throne from his treacherous brother. Failure will mean Casiopea’s demise, but success could make her dreams come true.

In the company of the strangely alluring god and armed with her wits, Casiopea begins an adventure that will take her on a cross-country odyssey from the jungles of Yucatán to the bright lights of Mexico City—and deep into the darkness of the Mayan underworld.

Review: Gods of Jade and Shadow is an immersive historical fantasy set in the Jazz Age and is steeped in Mayan mythology. Casiopea Tun and her mother are treated horribly by their more wealthy relations. They work as servants rather than being acknowledged as part of the family. Casiopea has large dreams of following the stars like her namesake, but any dreams that she had has been dashed by her grandfather's demands. She has been his maid ever since they returned to their small village after her father's death. As a small act of rebellion, Casiopea opens her grandfather's secret chest, releases the injured and imprisoned Mayan death god, Hun-Kamé, Supreme Lord of Xibalba, and inexorably binds her to his quest to regain his underworld throne. Casiopea's journey with Hun-Kamé's not only changes her fortunes but also has a largely consequence on the fate of the world.
  I really enjoyed the blend of historical fiction along with learning new things about Mayan mythology. The world building is done well and is not too out there for reluctant fantasy readers. It was fascinating to read about Mexican life during the Jazz Age. I liked watching Casiopea go on a self discovery journey to learn about herself and become an advocate for herself. Similarly, her interactions with Hun-Kamé allows him to become much more than an avengeful god and be humanized by addressing his own fears and vulnerabilities. I also enjoyed their slow burn romance. The plot moves quickly as we follow two parallel journies of  Hun-Kamé and Casiopeia's cross-country adventure-from the Yucatán to Mexico City, Arizona, and more-in search of his missing body parts, which his twin brother and rival has scattered among demons, sorcerers, and others; and Vucub-Kamé's, Hun-Kamé's ambitious twin brother, plot to undermine his brother and is assisted reluctantly by Casopeia's narcassitic cousin Martín who also has an inferiority complex. I would recommend this book to readers who are interested in learning more about Mexican folklore as well as those who enjoy reading fairy tales with complex characters and slow burn romance.
