The Book Of Gold By Long, Ruth Frances

There’s only one thing notorious thief Lyta loves more than a big score: her little brother, Kit. But when Kit is arrested for producing seditious pamphlets, he stands to lose not only his printing press, but possibly his life. In exchange for her brother’s freedom, Lyta strikes a daring bargain with the king – she will steal the infamous Book of Gold: a mysterious manuscript reputed to be hiding vast magical power within. It’s just the kind of challenge Lyta relishes, but she didn’t bargain for a secretive scholar, her brother’s interference, or the return of handsome and brooding Captain Sylvian Chant, once her lover and partner in crime, now an incorruptible royal bodyguard.
