Untamed Spirit (Freedom's Fighters, #2)

Her name is Grace, but she's Grit Tanner to almost everyone who knows her, a boy who'll do odd jobs and can ride any horse around. Now Grace is going west to the new land of Kentucky. She wants land and a new life, but to get there she'll have to travel down the Ohio River by boat. Keeping her true identity a secret won't be easy, especially when a silver-eyed former British major is one of the passengers and sees right away that Grace is not who she pretends to be.
