Vibrations in the Field by Daniel Burke

Jane Carter, a brilliant PhD student in quantum physics, seeks treatment for hallucinations of visitors from other universes. She turns to Dr. Barry Lieberman, who uses hypnosis to split her personality and commits her to a mental hospital. After meeting combat veteran Joe, she sets out for justice against Lieberman, who will use his darkest psychology and cruelty to stop her. Good men take the Hippocratic oath, but evil ones like Lieberman break it. Sweet Jane learned that firsthand.
