Blood and War by Belle Walker

A fated encounter. A forbidden romance. Together, they can change everything…

For ten years, Demitria Collins has fought the creatures of nightmares to protect the one person she has left. With a rising string of demon attacks on the forefront, she knows it’s only a matter of time until they’re next.
But when a routine patrol goes awry, and Demitria has a fated encounter with the legendary Horsemen known as War, everything she fought for is threatened. Including her life.
Kellan, one of the Four Horsemen of the Apocalypse, has been sent to Earth by the High Council of Eden to restore the balance with his siblings. Dispatched on their newest assignment, he expected the task to be simple. Not for his charge to be human.
When a split-second decision leaves even more blood on his hands, Kellan has questions for the council – ones they won’t answer.
The Horseman should embody everything Demitria hates, but a growing darkness forces them into an uneasy allegiance to uncover a deadly truth. An inexplicable attraction complicates matters even worse, transforming their hostility into something beautiful and fiery that breaks through every belief they’ve ever had.
Both know the consequences of those feelings will be deadly.
But together, they might stand a chance to restore order before the ultimate destruction of a planet that she, and the High Council, hold dear.
