Sisters of the Fire (Daughters of the Storm Book 2) by Kim Wilkins

Short profile:

Four years have passed since the five royal sisters—daughters of the king—worked together to restore their father to health and to the throne while fracturing the bonds among themselves almost irreparably. Only Bluebell remains at home, dutifully serving as heir to her father’s kingdom. Rose has been cast aside by her former husband and hides in exile with her aunt, separated forever from her beloved daughter, Rowan. Ash wanders the distant wastes with her teacher, learning magic and hunting dragons, determined that the dread fate she has foreseen for herself and her loved ones never comes to pass. Ivy rules over a prosperous seaport, married to an aged husband she hates yet finding delight in her two young sons and a handsome captain of the guard. And as for Willow, she hides the most dangerous secret of all—one that could destroy all that the sisters once sought to save.
