Threshold of Danger (A Guardian Time Travel Novel Book 1)

USAF Pilot Elliot Knight’s days of jumping without a safety net are firmly in the past. There’s nothing and no one that would ever convince him to dust off his time travel gear and take the ultimate leap.

That was before Samantha Billings showed up on his radar with her foundation built on saving lives. Before her sister showed up on his couch half-dead.

Hope Alive Operative Samantha Billings’ life has been limited by a past she can’t change and an ex-husband who won’t let her go. An ex-husband who is convinced her sister is responsible for a recent attempt on Sam’s life.

As a former Foreign Correspondent, Haley Billings has been around the globe sharing stories of both extreme heroism and violent tragedy, including that of her own dark hour. The one that sent her into the clutches of severe alcoholism interrupted only by implicating memories and a host of secrets she can never share. Not even with her sister, Sam—the only person who hasn’t given up on her.

Captain Simon Riley would love nothing better than to put Haley Billings behind bars where she can’t hurt anyone ever again with her exaggerated articles. Where her stories are only just that. But he’s already been down this road. One that resulted in two unnecessary deaths. A preventable suicide. A missing girl.

When a woman who was brutally murdered six months earlier reappears, Haley knows her secrets can’t be hidden any longer—even the ones lost in the abyss of her mind. And Simon knows none of them are safe. Because whatever Haley has done—or not done—is coming for her. Coming for Sam. Coming for Elliot.

Enticing them across the threshold. Right into the hands of danger.
