She Who Would be King

Cateline is the seventeen-year-old daughter of a nobleman in fourteenth-century France. It's a time when children aren't seen as those to be loved and cherished, but instead are used as pawns and bargaining chips on the chessboard of control and privilege.
She is married off to a prince in the country of Sursha, a Gaelic-speaking island nation near Ireland. Fergus, her betrothed, is next in line to take over once beloved King Carthac dies. Or is he?

Fallon, the youngest royal child and only girl, has been raised as one of the king's sons her entire life, for reasons she has never fully understood. A natural fighter, she was raised to be a warrior and head the Crown's Elite Guard assigned to protect her boorish brother Fergus.

Forced to fill in for her brother in an unexpected way, an instant attraction between Fallon and Cateline forms. In a game of thrones filled with deception and betrayal, even the most secret love can mean death.
