The Foxling Soldati. Soldati Hearts, #2

Foxling Toka has served the Soldati king for centuries, and now he attends to the kingdom's cherished Soldati prince. It's a position of honor, and as Toka helps the once-human prince adapt to their magical realm, he finds joy in their friendship. He also grows bolder in his encounters with Rayner, Soldati warrior and the king's second. But the laws are clear: servants and Soldati are not permitted to mate.
It doesn't matter that Toka lost his heart to the dashing cad long ago. Rayner never imagined he would fall in love with a servant, but the clever and beautiful foxling has ensnared him, and he resents the regulations keeping them apart. When an arrogant and spiteful king visits from a neighboring realm, Rayner is in danger of losing everything. But Soldati warriors don't surrender, and he intends to fight all the harder to keep Toka where he belongs-in Rayner's arms.
