When Dr. Olivia Mills gets a call from a man who wants to hire her to kill her boyfriend, she knows her cover is broken and her former life as a CIA assassin has come back to plague her. Determined to keep her boyfriend safe, she drives him straight to Washington, to visit her former boss and find out who reactivated her code name. When she gets there, she learns it was all a ruse by her ex-lover, ex-Interpol agent Holt Landry, to clear her name from a past assignment gone bad. Past Sins (3), by Debra Webb, is a fast-paced story. Although the characters are interesting, they could be better developed.
