The first three books in the Bullet Catcher series are 1) KILL ME TWICE; 2) THRILL ME TO DEATH and 3) TAKE ME TONIGHT. They are not a trilogy, but feature some of the same characters, all part of the Bullet Catcher organization. They are all in print and available. The next three books in the series (FIRST YOU RUN, THEN YOU HIDE, NOW YOU DIE) are also stand alone, but do include a story thread that arcs over all three books and ties them together. But my goal as a writer is to ensure that a reader can read any of the books alone and never feel like they've missed something, or read them in order and get a sense of continuity and enjoy recurring characters.
