The Flip. Psy Squad, #6

Emily Storey has just flipped her entire life: new town, new apartment, new roomie, new job. She has also gone blonde and lost some weight. What Emily hasn't managed to do is kick other people's random thoughts out of her head. That's no easy feat for a psychic, especially one who has spent the last three years training to enhance her abilities, not suppress them. Emily volunteers to feed the homeless one night a week, hoping she can help change other people's lives, too.
But her good intentions are annihilated when Detective Bastian Rossi, a cop who talks about safety at her orientation meeting, warns them all against giving rides, loaning phones, or offering shelter to the street people they're feeding. Homelessness, he tells them, is a chronic problem that no single person can solve. All they're supposed to do is hand out sandwiches. In spite of all that, Emily's first night on the street with her assigned partner goes very well until she begins intercepting random thoughts of the people they're feeding.
One voice is particularly threatening and seems to be directed at her. Though Emily could easily confide in Detective Rossi she hesitates. Bastian already has his hands full with a local serial killer. She can definitely take care of herself.unless the guy inside her head is the evil murderer he's trying to find.
