BURN THE KINGDOM DOWN by Addie Thorley

A standalone YA romantasy filled with a romance that will leave you breathless, betrayals that will rip your heart out, and a princess who will stop at nothing for revenge. Sourcebooks published in April 2026.

One year ago, Rowenna Harrack, the crown princess of Tashir, left her homeland in a wedding dress of chains—sent away to the enemy nation of Vanzador as a captive bride.

Now, Rowenna is dead. Brought home in a coffin after an alleged fall from a cliff.

Second-born princess, Indira, knows her sister's death was no accident. Desperate for truth and vengeance, Indira agrees to wed the prince so she can infiltrate Vanzador, find Rowenna's murderer, and burn their kingdom to the ground.

Indira's plan is simple: she will make nice until she can find out how to avenge her sister and free her country from the rival nation's stranglehold. But when Indira arrives, nothing is as terrible as Rowenna described. As Indira grows closer to her new husband, Prince Alaric, and uncovers more about Vanzador, the source of its powers, and what happened during Rowenna's final days, she's no longer sure what—and who—to believe. Because everyone, even her sister, has secrets. Deadly ones.

Action-packed, twisty, and romantic, BURN THE KINGDOM DOWN is a thrilling addition to the romantasy genre.

Following her sister’s suspicious death, a girl vows to uncover the truth and avenge her.

Indira Harrak is shocked to learn that her older sister, Rowenna, the crown princess, has died under mysterious circumstances while serving as a captive bride in the kingdom of Vanzador. Plagued by Marauders, the kingdom of Tashir was forced into a harsh treaty with Vanzador that included tributes of bagrava, the sacred plant that keeps Tashir fertile and can only be cultivated by master gardeners like Indira. The treaty also required a Tashiri princess as a bride. In return, the Vanzadorian king created a mountain range to keep invaders out of Tashir. To protect her people, Indira must now marry her sister’s widower—and possible murderer—Prince Alaric. When she arrives at Vanzador’s mountain Fortress, nothing matches the terrible descriptions in Ro’s letters. Indira is convinced that the differences are a clue to something her sister wanted her to know. She also uncovers the reason for the Vanzadorians’ endless demand for bagrava. As Indira navigates the Fortress, intriguing characters lead her toward the truth—and attraction sparks between her and Alaric. The deeper she ventures into Vanzador’s mysteries, the more Indira questions how well she knew Ro and what secrets her new home may be hiding. Thorley skillfully blends political intrigue, romance, magic, and mystery into a story filled with betrayals and shocking reveals that build toward a thrilling conclusion. All main characters are light-skinned.

A page-turner that’s filled with twists and turns. (Fantasy. 14-18)

I'm delighted to share this nice review from Booklist:

Burn the Kingdom Down.

By Addie Thorley

Apr. 2026. 448p. Sourcebooks/Fire, $19.99 (9781728283036). Gr. 9–12

Indira and Rowenna, princesses of the nation of Tashir, were never alike. Indira was happy to stay quiet and tend to the fields of bagrava, their main crop for the sustenance of the people and for export. Rowenna was bigger, brighter, better—a fighter in the armies, a politician in the castle—so she’s the one chosen to marry their sometimes ally from the neighboring nation of Vanzador. It’s less than a year after her marriage that Rowenna returns to Tashir, this time in a chained coffin. To save their crops and her people, Indira steps up to marry the prince, keep the tenuous peace, and perhaps exact revenge. What she discovers in the mountains of Vanzador is a magic stranger than she expected and secrets that lead her to a wholly different picture of her sister than she’d even seen before. Will she still need her revenge as she sees what lies beneath the earth magic of the new kingdom? Thorley excels at creating sweeping kingdoms like Vanzador and Tashir, incorporating unique magic systems both intriguing and clever.
