About this audiobook

Caleb Thorne lives by a simple, ruthless code: win at all costs. In the billion-dollar war for Apex Technologies, his sole focus is crushing his fiercest competitor, the brilliant and guarded Sloan Madison. But when a single photograph reveals Sloan with a one-year-old boy who has his unmistakable eyes, the battlefield irrevocably shifts from the boardroom to the nursery. Forced into a tense confrontation, Caleb discovers Sloan has been playing a different game entirely—one where the stakes aren’t just stock prices, but the life of the son he never knew he had. His instincts scream for a hostile takeover, but his father’s brutal playbook won’t work when it comes to family. Just as they forge a fragile, distrustful truce, a ghost from their past emerges to hunt them both. An old enemy launches a catastrophic attack, targeting not just their empires, but their children. Now, Caleb and Sloan must form an unwilling alliance, a dangerous merger of enemies.
