Book trailers are often kind of underwhelming — but every now and then, you get one that feels like it should be an actual movie. Like this trailer for Scott Sigler's new monster-filled novel Nocturnal, which he's describing as "Lethal Weapon Meets Hellboy." Some of the most beautiful carnage we've seen in ages — plus it really is true that you have to keep watching until the end, because the final few seconds are a thing of beauty.
