An Extraordinary Union — Alyssa Cole

As the Civil War rages between the states, a courageous pair of spies plunge fearlessly into a maelstrom of ignorance, deceit, and danger, combining their unique skills to alter the course of history and break the chains of the past . . .

Elle Burns is a former slave with a passion for justice and an eidetic memory. Trading in her life of freedom in Massachusetts, she returns to the indignity of slavery in the South -- to spy for the Union Army.

Malcolm McCall is a detective for Pinkerton's Secret Service. Subterfuge is his calling, but he's facing his deadliest mission yet -- risking his life to infiltrate a Rebel enclave in Virginia.

Two undercover agents who share a common cause -- and an undeniable attraction -- Malcolm and Elle join forces when they discover a plot that could turn the tide of the war in the Confederacy's favor. Caught in a tightening web of wartime intrigue, and fighting a fiery and forbidden love, Malcolm and Elle must make their boldest move to preserve the Union at any cost -- even if it means losing each other . . .
