The God of Thunder faces the fury of living planets. When terrible storms threaten to tear our world apart, Thor traces the cause to Ego, the Living Planet out of his orbit and rocketing across the solar system on an unstoppable quest to rescue his long-lost brother, held captive by the cosmic entity the Collector. But there will be no happy reunion at the end of his journey for when Ego and Alter-Ego meet, only one can survive…and Earth surely will be destroyed. Only Thor has power enough to avert the pending apocalypse but to do so, he’ll have to rely on the help of a wind goddess with questionable motives…and a stormy history with the God of Thunder. Collecting ASTONISHING THOR #1-5.
