She ran from human monsters. She was caught by something far more dangerous—and far more possessive.

Kiva has survived three years as a slave in Warlord Skaz’s brutal fortress. When she finally escapes across the scorching salt flats of Xylos Prime, she expects to die free rather than live in chains.

She doesn’t expect to be rescued by seven feet of scaled muscle, golden eyes, and predatory hunger.

Zirak is a Sun-Spear—an elite warrior of the Saurian Vang. His cold-blooded people crave heat, and this soft, warm human female ignites something primal in him. When he claims her as his Foundling, he stakes his own life on her loyalty. If she betrays his tribe, they both die.

But Kiva has no intention of betraying the only beings who have ever treated her as more than property.

As war looms with the Dust-Walker raiders, Kiva must prove her worth to a tribe of reptilian warriors who see her as an outsider—or worse, a threat. And Zirak must convince his people that the soft-skinned female who sets his blood on fire is worth protecting, even if it means awakening the World-Eater itself.

In a world of triple suns and ancient monsters, two souls from different species discover that the fiercest heat burns between scales and skin.
