A healer raised to serve a sacred order. A warrior fighting to destroy its darkest secret. And a forbidden bond that means if one of them dies, so does the other.

Iyla has spent her life within the temple walls, training to wield the blood-and-earth magic of the Magini and create the precious gold-blood that sustains her people. She knows the rules. She knows her duty. And above all, she knows the Valashi are monsters.

Until she saves one.

When a dying Valashi commander falls into her hands, Iyla makes a choice that should condemn them both. Her blood heals Kian—but the magic goes horribly wrong, binding their lives together. Now the temple can sense the forbidden Valashi magic inside her, and Iyla has only one chance to escape execution:

Flee with the enemy she was taught to fear.

Kian is powerful, infuriating, and determined to uncover what the Magini have done to his people. But the farther Iyla travels from everything she has ever known, the more impossible the truth becomes to ignore. The sacred traditions she devoted her life to may be built upon something monstrous. The raids she was taught to fear may not be what they seem. And the warrior whose life is tangled with hers might be the only person she can trust.

With war closing in and their unwanted bond growing stronger, Iyla must decide how much she is willing to sacrifice for the truth—and what happens when the man who should be her enemy becomes something far more dangerous.

Because blood may have bound their lives.

But choosing each other could cost them everything.

Perfect for fans of Carissa Broadbent, Danielle L. Jensen, and Penn Cole, A Vow of Blood and Gold is an epic fantasy romance featuring forbidden blood magic, enemies-to-lovers tension, found family, a morally complicated war, and a heroine forced to question everything she was raised to believe.
