The condition is simple but impossible. Isabella must marry Alexander Blackwood, the powerful billionaire heir known throughout New York as the Ice King. Alexander Blackwood wants nothing to do with the arrangement. Isabella wants even less. But refusing the marriage would destroy everything both families have built. Forced into a union neither of them wants, Isabella and Alexander become trapped in a relationship built on resentment, suspicion, and secrets.

Buried deep within the past lies a dark secret connecting their families. Years ago, a terrible crime changed the course of both their lives. Someone manipulated the truth, ruined innocent lives, and ensured that the secret remained hidden. As old enemies resurface and dangerous truths begin to emerge, Isabella discovers that her father’s will contains more than a marriage clause. It contains the key to a mystery someone is willing to kill to protect. In a world where trust is dangerous and love is even more dangerous, Isabella must decide whether the man she was forced to marry is her greatest enemy or her only chance at uncovering the truth.
