She loved...and lost.

Ruby Jane never thought she'd meet the man of her dreams while running from the police in Russia. That he'd steal her heart on a train to Siberia. But loving a former CIA officer comes with a price...a life of danger. A life of high stakes.

A life where he simply disappears...

He has no memory of the man he was.

Mack Jones has no memory of his past...just the dark sense that he is hiding. And, he wants to stay that way. Mack likes the life he's built in a small tourist town, tucked away beyond the mountains, and has no desire to dig around in the gray areas of his memory.

When his place of business catches fire and Mack rescues the owner, he makes the news, which of course alerts the past he's hoping to outrun.

The only person who can help him is a mysterious woman he doesn't remember.

But a woman he desperately needs.

The surprising, thrilling conclusion to the Montana Marshalls series.
