Thor: Reign of Blood #1

The daughter of the frost giant slain in "Ages of Thunder" has brought about a devastating winter in her grief, which is only stopped through the forging of some exceptional items by dwarves. The Enchantress acquires one such item in a way that no man could, and angers Odin, who takes it from her. She then causes the dead to rise on Midgard, and it is up to Thor to hold back the tide.
