The God Machine
From a coveted styrofoam cup that Elvis reputably drank from to ancient petrified dieties are all items used to bring back an avenging angel of destruction into corperal being. First things first, the good guys don't know why, and when they find out its just a little too late before he get here, and Hellboy has to put him back in his place. There is also this crazy thing going on with the undead being found stuffed full of seemingly unconnected clockwork parts and wires to make them come to life and act as obedient goons. There is also a talking dog. Creeeeeepy! So far one of my favorite Hellboy novels yet.
