The Stormbound Knight by Amy Pennza

Seize the tempest. I’ve spent my life doing just that—harnessing wind and lightning to protect the vulnerable. But I’ve never quite belonged. The son of an elven mother and human father, I straddle two realms: the elven lands where I’m shunned as an outsider, and the human world where I’m viewed as useful but suspect. Forbidden to take a wife or sire children, my service as a celibate knight has given me purpose.
But now, I’ve been summoned to dangerous territory.
When the lords of the Spring Court ask me to aid in their battle against the monsters that threaten both of our worlds, I answer the call—and step into a whirlwind of duty and desire. The politics of the Spring Court are as volatile as the storms that surround the kingdom. But my forbidden attraction to King Tanyl poses the most risk. As charming and gallant as I remember, he draws me like a parched man to water. And when I meet his alluring queen, I find myself entangled in a web of powerful magic I’m ill-prepared to resist.

Torn between piety and desire, I must fight a war on two fronts. As the monsters multiply and Tanyl’s crown is threatened by enemies from within, I’ll risk everything to help my friend and his wife. But as blood flows and betrayal comes from an unexpected source, I’m confronted with a bitter truth. I can keep my life, my vows, or my heart—but I can’t keep all three. And when the storm finally passes, I might end up losing everything.
