Thor: Gorr The God Butcher [Marvel Premier Collection]

Gods are vanishing across the ages, and Thor must unravel the gruesome mystery of Gorr the God Butcher. In the distant past, Thor discovers a cave echoing with the cries of tortured gods. In the present, he follows a bloody trail of murdered deities through the depths of space. And millennia from now, the last god-king of Asgard makes his final stand against Gorr's berserker legions.

As three Thors from three eras race to stop the killer, the full scope of his plan emerges: the Godbomb, a machine built by enslaved gods that could forever reshape creation. United across time, will the three Thunderers be enough before the weapon is triggered? Collecting Thor: God of Thunder (2013) #1-11.
