Sierra Wallace hates Ian Raeder for making her teenage years a misery with his mockery and constant teasing. But he's so damn hot! Just the sight of him turns her insides to molten lava. Ian's hunger for Sierra is driving him insane. But he's a Shifter, a leopard in his other form, and she's human. He has to stay away from her. When enemy Shifters invade Wade County, Colorado, Sierra and Ian are caught in the crossfire. As they fight to keep each other alive in a war that threatens to destroy every Shifter in the county, barriers tumble. The driving force of their long-suppressed passion explodes into sheet-scorching animal lust. In the torrid nights that follow, they discover that their firestorm of love and desire is far more devastating to them than any war.
