The Matthew Corbett books have historically been hefty affairs—Speaks the Nightbird, the first in the series, clocked in at over 800 pages, and the others have gone 400 or more. The lone exception was the fifth book, 2014’s River of Souls, which was a lean 256 pages. It’s my personal favorite of the series, the perfect mix of Robert McCammon’s incredibly detailed world building and action/thriller pacing.
Freedom of the Mask has put some of the weight back on—my advance copy hit 530 pages—but maintains the breathless pace of its predecessor. There’s enough story packed in it for two books, but it’s filler-free, and for good reason: there’s a ticking clock hanging over McCammon’s head now. He’s announced that the series will go nine books and no further, which puts us deep in the overall Corbett story arc at this point. McCammon is very calculated in the way he handles each book’s immediate plot while moving all the pieces toward the series conclusion.
