Even the best magical tools in the world cannot always predicted impending disaster, but at least this one's close to home. Still, a smoking pile or rubble where a bookstore should be in this case is a good sign that the team is too late (in other cases it could indicate that Bookburners were already there...).
The Bookburners have a collector to deal with, entangled civilians, and a leaking demonic book.
Just another day at the office?
Excellent continuation of the series, it just keeps getting better.
