Reckless by Beth D. Carter

When a tragic accident changed the course of his life, Mason Lake was forced to leave his Apache roots behind. He made a life for himself at Harlan Securities, being known as the calm, rational man who runs the office. He also lives with the love of his life, Carrie Fenway.
Yet the past never truly stays dead. When they discover that they’ve been hacked and deceived, he and Carrie investigate, revealing a threat that Mason thought long gone.
Even as he tries to maintain control, Carrie’s life is thrown into danger, forcing Mason to reconcile with the recklessness that’s always lingered under the surface of his calm demeanor.
