Her secret mission. A country divided. His impossible love.

Henrietta Wright is a Free Colored woman who teaches reading and writing to anyone who enters her classroom. At least she was, until a drunken night with friends catapults her down a path of intrigue, coded messages, and intelligence operations. All in service of the Union Army. She can't tell anyone what she's doing, including the handsome Irishman she knows she shouldn't want, but can't seem to resist.

Since stepping onto American soil, Elijah Byrne's only goal has been to survive another day. That is until Henrietta burst into his life and made him want more. She was never meant to be his - her fiancé can attest to that - but she makes him long for things men like him aren't lucky enough to have. When she asks for his help, he can't resist tumbling with her into a clandestine expedition that could cost them everything—including their lives.
