Firestorm by Iris Johansen

Trask is a man obsessed with fire who has created a lethal weapon harnessing its power. His test subjects are humans who get in the way of him and his "baby". Enter Kerry, a woman with the unusual gift of sensing when arson is at work, and Silver, a man who can hear the thoughts and feel the emotions of those around him. Kerry and Silver race to capture Trask before any more lives are lost. This is a paranormal, psychological thriller that I found hard to put down. 339 pages.
