Rule of Claw by Milly Taiden

He rules the battlefield. She rules her fists. Together, they might just save a kingdom.
Jade Moreno lives and breathes martial arts. Teaching at her dojo keeps her grounded, but it also reminds her she’s alone—strong enough to fight anyone, yet no one strong enough to stand with her. Until the infamous Gerri Wilder steps into her life, promising her the adventure of a lifetime and a man who can match her strength.
General Raikar Veyth is the most feared panther shifter in Nova Aurora’s southern jungles. Disciplined, ruthless, and loyal to his kingdom, he’s conquered countless enemies—but the council won’t name him High Commander until he secures a mate. Love is the last thing Raikar has time for… until he lays eyes on Jade, and his panther roars: mate.

But enemies circle the borders, political rivals whisper betrayal, and Jade’s fiery independence challenges Raikar’s every instinct. To protect his kingdom, he must trust her as his partner—not just in battle, but in love.
