It' s a hot, hot summer, and in the depths of the Toronto Transit Authority' s Lost and Found, 17-year-old Duncan is cataloging lost things and sifting through accumulated junk. And between Jacob, the cranky old man who runs the place, and the endless dusty boxes overflowing with stuff no one will ever claim, Duncan' s just about had enough. Then he finds a little leather book. It' s a diary filled with the dark and dirty secrets of a twisted mind, a serial killer stalking his prey in the subway. And Duncan can' t make himself stop reading.
What would you do with a book like that? How far would you go to catch a madman?
And what if time was running out. . . .
