Book excerpt: Jason Aaron and legendary artistic collaborators including Esad Ribić and Russell Dauterman begin a truly epic saga of Thor -- whoever he or she may be! Across the ages, gods are vanishing -- and the God of Thunder must unite with his past and future selves to stand against Gorr the God Butcher! Meanwhile, Malekith the Accursed begins a bloody rampage that will spread war throughout the realms. Which makes it a terrible time for the Odinson to be rendered unworthy of lifting Mjolnir! Another hero will hold the hammer high, fighting for Asgard and Midgard as Thor -- the Goddess of Thunder! She'll battle Malekith, Loki, Roxxon...and even Odin! But who is she under the mask? And what is this new Thor's terrible secret? COLLECTING: Thor: God of Thunder (2012) 1-25, Thor (2014) 1-8, Thor Annual (2015) 1, Thors (2015) 1-4, Mighty Thor (2015) 1-12
