This author is talented enough to keep a reader on the edge of their seats, teetering between "tension and suspense" throughout. The characters seem real, and in the back of your head, you begin to wonder: who is really conning whom? You're completely drawn in, and you come out feeling your heart beating faster. Take a chance, you won't be sorry!
