For twelve generations, Le Couteau Noir has been under the rule of the House of Gunn.
With thirteen seasons, Sunni Gunn is the youngest Apprentice Adept in the history of Le Couteau Noir assassins. She has surpassed even her mother, Soniah, now the Gynrahl of the House of Gunn. For Sunni, life on Alcamene is one of regimented training and contracted killing. A chance meeting brings peaceful Wyatt into her life. He is a censeur, a telekinetic with a life very different from Sunni's. As the two become friends, they discover one of Alcamene's oldest secrets.
Political treachery and accusations against Sunni and Wyatt for unsanctioned murders threaten to destroy the House of Gunn and Sunni's world. Their new found friendship is put to the test as they are forced to battle traitors, cheats and thieves. Sunni is the rightful heir to the Gynrahl, but her enemies are determined to keep her from taking command. She and Wyatt are unlikely allies in the battle to clear their names.
