Queen to the Sunless Court (Brides of Myth, #2)

The divine trials are meant to break them. Their forbidden love could save them.

Calliste never expected to fall in love with a godless king. When her jealous patron god discovers her secret, he vows to have her at any cost—even if that means stranding her in the Underworld. It’s there that she learns Theron’s own dark past has come for his son.

Theron never dreamed the beautiful priestess was involved with the same Underworld gods he despises. But when her efforts to heal his son leave her near death, he realizes he’s fallen harder than he could ever imagine. As his harrowing past and cruel gods threaten Calliste and his son, Theron is ready to defy the Underworld itself.

But Calliste’s return to the mortal realm is just the first step.
A vengeful goddess is poised to spark a war between the Underworld and Olympus using the prince—and her trials are designed to break both heart and soul.

Can their love withstand the worst the gods have to offer, or is it as doomed as the kingdom they’re trying to save?
