Her most important mission…and she can’t remember what it is.

After amnesia strands private investigator Emma Langston in Dallas, only Detective Ryder Palladin can stop the men trying to kill her. But protective custody on Ryder’s family ranch has its own risks, like falling for the handsome cowboy. Before she can untangle her feelings for Ryder, Emma must recover her memory…because she’s sure someone’s life depends on it, even if she can’t remember whose.
