The Wrong Path — Jane Glatt

Dani Norris found him: the dead guy. She was on her way home from her job in the PATH, the huge underground mall in downtown Toronto that connects hundreds of office towers, so it wasn't like he'd been there long. Even though he looked like he had.
After that weird things kept happening. Ro Parks from Sentinel Security seemed to have some answers but Dani didn't want answers. She just wanted things to get back to normal.
But they didn't: things just kept getting weirder. And more dangerous.
And weirdest of all? It seems that only Dani can make things normal again. She hopes.
