Merchants of Light and Bone by Erika McCorkle

Sorrow in paradise. A parent’s worst nightmare. When grief drives one to revenge. Living in a tropical paradise with his spouses and kids, Amiere is a merchant of light, a sculptor who carves glowing crystals into spectacular and powerful, demon-killing works of art. When the ground opens up near his idyllic village to reveal a massive supply of crystals, the whole nation of Aloutia celebrates. The merchants are guaranteed money for decades and officials predict Aloutia will be safe from demonkind for generations. But Amiere isn’t rejoicing—when the ground split apart, his seven-year-old daughter fell to her death. Amiere’s grief turns to rage when an old enemy returns to the village with a young daughter displaying signs of starvation and abuse. Having witnessed his own daughter’s death, Amiere cannot bear the thought of watching another child die, especially when he can prevent it. Unable to ask police for help due to the village’s reputation of hostility toward authority figures, Amiere takes matters into his own hands, even at the risk of being exiled and separated from his family forever.

Merchants of Knowledge and Magic by Erika McCorkle

On one of the many planes of the Pentagonal Dominion, priestess Calinthe trades in information, collecting valuable secrets for her demonic employer. Calinthe has a secret of her own: she's intersex, making her a target for the matriarchal slavers of the Ophidian Plane whose territory she must cross in her search for hidden knowledge. But thanks to her friend Zakuro's illusions, Calinthe presents as a woman—a comfortable, if furtive, existence in a world determined to bring her to heel. But when, instead of a mere secret, the priestess uncovers an incalculably powerful artifact, Calinthe finds herself in a high-stakes negotiation with the same matriarchs who sought to enslave her. On the table: Calinthe's discovery, a charm powerful enough to transform a mortal into a god… against a secret so deadly it could quell all life on every plane of the dominion. If Calinthe plays her cards perfectly, she and Zakuro could escape Ophidia wealthier than either of them ever dreamed possible. But if she plays them wrong… …she'll learn slavery in her pursuers' hands is a fate far worse than death.
