Love Tales from the Borun-Ma. The Borun-Ma Series, #2

The mountains of the Hoshien are home to the Sky Palace, the capital of Danau, one of the three independent regions of the Sixhen-Zha. In all of the Borun-Ma, this is the sole kingdom ruled by women, and only they can take the throne - every male born to the ruling Princess put to death mere seconds after their birth. And none of the Princesses have rebelled. They go to their labour knowing the child they birth might end up dead, willingly sacrificing them for the sake of their nation - such is their abhorrence for men's supremacy.
Until a new generation of heirs to the thrones of the Sixhen-Zha comes of age, aiming to change the world and restore justice. But what if the secrets they hide are just too dangerous, and not even love can save them?
