Joy Fielding: Trance (USA 1978)

From the Publisher:
The Senator's daughter. Three years ago they ravaged her body. Now, they'd come back for her mind...

SHE'S THE DAUGHTER OF THE NEXT PRESIDENT.
SHE'S A PROGRAMMED KILLER LOCKED IN A TRANCE.

Sandy Renford had always loved her famous and powerful father -- and hoped he'd live forever. Then the kidnappers exploded into her world. Every day. Every night. Every hour... they taught her the same cruel lies. Probed her rich-girl sins and buried fears. Stirred the old sleeping guilts and terrible desires. And told her he deserved to die. Until she began to believe them. Until she wanted to kill him...
