A prophecy casts its shadow over two kingdoms—and over two people whose destinies are entwined even before their births.

Grayson, Lord Wolfe, is happiest when designing new innovations to help his people. He is also a warrior out of duty to his king and uncle. Called to fight in a border skirmish, Gray defeats the enemy. . .with an unintended consequence. Highborn Lady Stefanie Falkon is taken prisoner and given to him as a slave.
Stefanie arrives at Wolf's Lair, the castle of Lord Wolfe, her new master. Her anger, resentment, and humiliation soon turn his organized world to chaos. His feelings are almost as strong as hers. She's destroying his concentration and distracting him from his work.

But betrayal and magic threatens both their kingdoms. Can they overcome their enmity long enough to save their lands and themselves?
