In a gritty medieval world where the ruling houses are based on the constellations, betrayal, intrigue, and a king's murder force the royal sisters of the Bear House on the run!

Moody Aster and her spoiled sister Ursula are the daughters of Jasper Lourdes, Bear Major and high king of the realm. Rivals, both girls dream of becoming the Bear queen someday, although neither really deserve to, having no particular talent in... well, anything.

But when their Uncle Bram murders their father in a bid for the crown, the girls are forced onto the run, along with lowly Dev the Bearkeeper and the half-grown grizzly Alcor, symbol of their house. As a bitter struggle for the throne consumes the kingdom in civil war, the sisters must rely on Dev, the bear cub, and each other to survive—and find wells of courage, cunning, and skill they never knew they had.
