Press notes for Bird House read: "An army of puppets and a magical wind create two fantastical worlds. On The Bright Side, Louisy and Syl live happily together in the safety of their treehouse until Syl ventures off to be a hero in the far away war-torn Lop Side. Alone for the first time, Louisy falls victim to the whims of tiny creatures at her doorstep. When the two sides collide, impossibilities become real, and both realize the lines between right and wrong are not as clear as they thought."

Marks' plays include A Chicken Goes to Broadway, Flyers and Other Tales, Ark, I-95 South and The Patriots. She has penned the screenplays for "Mouse Hole," "Jumped" and "Wanted."
