The Sensation Inside

Merry awoke that day with a strange sensation inside. As she planned out a cross-country trip with friends, she began to feel that she had no control over her actions.
She was driven to follow the maddening voices she heard and to understand the elusive clues she had stumbled upon. They would begin this trip as four friends, but they were not alone.
What really happened to Neffertiti, the famous Egyptian queen? And what did this have to do with Merry and her friends? There had been a grave injustice in the past, and someone was mirroring past events in this time.
Someone was trying to make things right this time.
The FBI had become involved after they found the first body. Can Merry solve this intricate puzzle before the FBI does? Or will someone make her the next casualty?
