Unstoppable

Summary: "Love with the Proper Stranger" FBI agent John Miller was on the trail of a notorious female serial killer, and he couldn't blow his cover to anyone. Not even the beguiling Mariah Carver, who had unwittingly entangled herself in a web of deadly deceit. The daring lawman couldn't deny his feelings for Mariah, but he was poised to wed another woman: the ruthless Black Widow, who marries--then murders--her victims. "Letters to Kelly" For years, a trumped-up charge--and a Central American prison cell--kept Jax Winchester from claiming the girl he loved. Now he was a free man. Or was he? He was still a prisoner, in a jail of his own making. The way out this time? Keep that promise he'd made to Kelly O'Brien all those years ago--and claim her for his own.
