Her battles against Frost Giants, Malekith and the Minotaur prove that she is well worthy of the name Thor! But this new hero is secretly Dr. Jane Foster — and each time she transforms, it worsens the cancer that is killing her! As the Odinson comes to terms with the loss of his hammer, the new Thor defines her independence when she battles Odin himself! But will she prevail when she is caught between Roxxon and S.H.I.E.L.D.? Meanwhile, Malekith is waging war across the realms — and Jane must lead a powerful new League to oppose the Dark Elf’s terrible plans!
