Interplanetary intrigue and romance combine in this electrifying finale to the Consortium Rebellion series.

As the youngest member of her High House, Catarina von Hasenberg is used to being underestimated, but her youth and flighty, bubbly personality mask a clever mind and stubborn determination. Her enemies, blind to her true strength, do not suspect that Cat is a spy—which makes her the perfect candidate to go undercover at a rival House’s summer retreat to gather intelligence on their recent treachery.

Cat’s overprotective older sister reluctantly agrees, but on one condition: Cat cannot go alone. Alexander Sterling, a quiet, gorgeous bodyguard, will accompany her, posing as her lover. After Cat tries, and fails, to ditch Alex, she grudgingly agrees, confident in her ability to manage him. After all, she’s never found a person she can’t manipulate.

But Alex proves more difficult—and more desirable—than Cat anticipated. When she’s attacked and nearly killed, she and Alex are forced to work together to figure out how deep the treason goes. With rumors of widespread assaults on Serenity raging, communications down, and the rest of her family trapped off-planet, Catarina must persuade Alex to return to Earth to expose the truth and finish this deadly battle once and for all.

But Cat can’t explain why she’s the perfect person to infiltrate hostile territory without revealing secrets she’d rather keep buried. . . .
