Adrienne Kress is a Toronto-born actor and writer. Her books include the award-winning and internationally published novels Alex and the Ironic Gentleman , Timothy and the Dragon's Gate , and Hatter Madigan: Ghost in the H. A. T. B. O. X. (with bestselling author Frank Beddor), as well as Steampunk novel The Friday Society and the gothic Outcast . She is also the author of the quirky three-book series The Explorers . Adrienne's first foray into writing horror came with her work on the Bendy and the Ink Machine novels, but as an actor she has had the pleasure of being creepy in such horror films as Devil's Mile and Wolves . And she took great pleasure in getting to haunt teenagers in SyFy's Neverknock .
