Fire Witch (Hot Hex 4). Hot Hex, #4

A Viking king out of time. A fire-forged witch who refuses to kneel. A destiny written in smoke, steel, and seduction.  Isla Sinclair has finally earned her place as the island's blacksmith-strong, skilled, and fiercely independent. She's more comfortable with a hammer in her hand than a man in her bed. But when a towering stranger steps out of the Scottish mist, all muscle, menace, and molten heat, Isla's world tilts.
Ragnar Rask, Viking king of 800 A. D., has crossed centuries in search of a queen worthy of his shield and his bed. One look at Isla-her fire, her strength, her refusal to be intimidated-and he knows the gods have answered him. But claiming her means dragging her into his own time. and straight into a war he may not win. An evil priest has risen in Ragnar's absence, wielding dark magic powerful enough to destroy his people.
Only a Fire Witch can stand against him-and Isla's untamed power may be the key to saving Ragnar's world. But embracing her magic means embracing Ragnar. And loving a Viking king means risking everything. As passion ignites and danger closes in, Isla must decide whether to remain in the world she knows. or step into a past where a fierce, irresistible warrior is ready to fight-and burn-for her. A time-twisting, heat-drenched fantasy romance where a modern blacksmith meets her match in a Viking king determined to claim his queen.
