Ghost Walk [EPUB ebook] 

This is no dream…Nikki Du Monde’s newest employee is standing at the end of her bed at four o’clock in the morning begging for help. It’s a joke, right? Besides, as manager of a successful New Orleans haunted-tour company, Nikki doesn’t scare easily. But in the light of day, harsh reality sets in as a police officer informs her that Andy was brutally murdered-at the exact time Nikki swears the distraught woman was in her room.No one believes her except Brent Blackhawk, a paranormal investigator desperately trying to forget his tragic past. Half Irish, half Lakota-and able to communicate with the dead-Brent is used to living in two worlds. But when he realizes the ghost of a slain government agent is also trying to reach out to Nikki, he knows that she, too, must listen to the dead…if she wants to keep living.
