Dark Deception — Nancy Mehl

Kate O'Brien's quiet life in small-town Shelter Cove, Arkansas is shaken when her past suddenly comes roaring back to life. Four years ago, she and her twin sister were attacked by an elusive serial killer. Only Kate survived, and she's been in witness protection ever since.

When new evidence arises to suggest the convicted man wasn't the murderer, she's subpoenaed to testify in the new trial. Afraid to go back into that world, Kate only agrees if Tony DeLuca, the deputy Marshal who protected her during the original trial, escorts her to St. Louis.

Tony readily takes on the assignment; Kate's beauty and inner strength made more of an impression on him than he expected. But when Kate's safety is threatened, Tony must race against the clock to keep her alive and put this ugly case to rest before anyone else gets killed.
