Book #1 of the bestselling Consequences series:
From New York Times and USA Today bestselling author Aleatha Romig comes a suspenseful thriller about secrets and deception, passion and love, choices and consequences.
Every action has consequences.
Waking in an unfamiliar bedroom in a luxurious mansion, Claire Nichols is terrified to discover that a chance encounter led her into the cruel hands of her abductor, Anthony Rawlings. Claire has no understanding of why she’s there, but it’s been made abundantly clear—she is now his acquisition and every action has consequences.
Learn the rules to survive.
Facing incomprehensible circumstances, Claire must learn to survive her new reality—every aspect of her livelihood depends upon the tall, dark-eyed tycoon who is a true master of deception. Driven by unknown demons, he has no tolerance for imperfection, in any aspect of his life, including his recent acquisition. Anthony may appear to the world as a handsome, benevolent businessman, but in reality Claire knows firsthand that he’s a menacing, controlling captor with very strict rules: do as you’re told, public failure is not an option, and appearances are of the utmost importance.
Captivate the captor.
To fit together the pieces of the puzzle, Claire must follow his rules. Will her plan work, or will Anthony become enthralled by Claire’s beauty, resilience, and determination, changing the game forever? If that happens, will either of them survive the consequences?
Nobody ever did or ever will escape the consequences of his choices.—Alfred A. Montapert
