A year ago, lawyer Grayson Wainwright's brother was killed due to faulty metal bridge braces. When Grayson files a wrongful death case against a company accused of supplying shoddy materials to the Transcontinental Railroad, he relishes his chance to achieve justice. Grayson’s two witnesses intimately know the accused, Leary Riddock--one is his wife, Loraine, and the other is his secretary, Catalina del Mar.

Catalina and her husband, Joaquin, moved west from Omaha, working at various jobs for the Union Pacific. But when their infant son died, Joaquin abandoned her in Cheyenne, and Catalina was forced to support herself. She became a bookkeeper in Riddock’s construction company and soon learned her boss was not a legitimate businessman. As soon as the facts are revealed about Leary’s embezzlement, she agrees to serve as a key witness.

Then Loraine is killed right before she is scheduled to testify, and threats prove Catalina is next. Now with an orphaned infant on his hands, Grayson must move heaven and earth to protect his beautiful remaining witness…and his heart.
