Perpetua's Toronto is slightly different from the Toronto we live in. For one thing, goblins and trolls live in it. And they both know how to dig down. Somewhere, I've posted a fantasy map of the new Toronto subway network, "if dug by trolls", and I'll post a link to it again once we have our cover reveal.

Have a look at the map (click to show full size)! There are a few Easter eggs for the Toronto blogosphere...
