Castle Walls by D. Jordan Redhawk

Princess Sabine Katerina Annaatje of Dulce is on the run outside the castle walls from a vicious invader who has killed her entire family and usurped her father’s throne. With only one man at arms and a faithful handmaiden, she barely escapes the invader’s clutches as he has vowed to leave no blood heir alive.

Stumbling into a camp of itinerant performers, Sabine hides her identity, becoming Katerin of Aimsbury. She learns to trust the leader of the traveling circus, Ros Adamsson, a bawdy woman who is half-rogue and half-gentlewoman. Trust may eventually blossom into more if Katerin can overcome her fear and conservative upbringing.

Meanwhile, the invader is still searching for her. A rumored uprising in the Dulce Province, a royal summons for the Adamsson Circus, and a traitorous servant all collide to reveal a secret even deeper than Katerin’s identity.
