Anna Key Marshall is about to get what she's always wanted: a baby. Granted, it's through a sperm donor instead of her ex-husband, but you can't have everything. She has no idea why someone wants her dead, but she'll do whatever it takes to protect her unborn child—even if it means turning to her ex, the Black Ops specialist who broke her heart.

Five years ago, British Intelligence agent Nick Marshall slammed the door on the woman who betrayed him. But now Anna's back in his life with a vengeance, pregnant and full of attitude. He'd like nothing better than to walk away, but with her life on the line, he has no choice but to do what he does best—protect her at all costs.

As old wounds resurface, Nick begins to doubt his version of what went down with Anna so long ago. And he begins to believe they might have a second chance together. But with Anna's would-be killer on the loose—it will take the full force and fury of his protective instincts, fueled by a powerful love he can't leave behind, to hold on to the woman he still loves.
