Street Series by Ryan A. Span

In the future, telepathy is no longer a fantasy; it's a job. Gina is a woman with no future trying to make her way on the Street of Eyes, where people go to hire the desperate and the suicidal for their unique services. She is one of the new underclass, who use "Spice"- a powerful drug that gives them the ability to read minds. The drug has only one downside- it drives the user insane.

Stranded in a hostile country, separated from her friends, and haunted by terrible visions, telepath Gina Hart is in a bad position. Worse, she might be the only one capable of stopping an all-out war between the people who want her for their own purposes. Now it's just a question of how much more she can take. The acclaimed STREET trilogy continues in this thrilling second installment.
