The Seekers (The Wainright Trilogy #2)
Sadie Cuffe, Sophie Cuffe

As a Cavalryman of faith-in-action, Lawrence resents his alter ego, especially when Rachel Hawksley steps into his world, heart, and soul. She’s pure stubborn Yankee on a mission of her own to cross enemy lines and find her MIA brother. She’s got a colt revolver hidden under her skirts, and she collects lost lambs of children and slaves like a bee collects pollen.
When she mistakenly tries to take the mentally-challenged Lawrence under her wing, things get complicated fast. Entangled in the subterfuge of Confederate secrets, double cross, and friends’ betrayal, Lawrence fights to get Rachel and those they love safely back home without blowing his cover.
When Rachel discovers she’s been duped by this gentle boy/man, the artillery fire on the battlefield is nothing compared to the friendly fire Lawrence must face to win her trust and prove he’s worthy of her love. In this deadly game of cat and mouse, where no one is who they seem, is there too much enemy territory to cross before Lawrence and Rachel can find each other and make it out alive?
