Seems like Thor has become unworthy to wield the hammer. A new Thor claims the hammer and is female. No one knows anything about her. She's not sure why the hammer has claimed her and she's off to fight the bad guys.
This is not a genre I read much. I felt like I dropped into the middle of the story although this is the first volume of Thor: The Goddess of Thunder. I know nothing of her past nor Asgard. It was confusing. This is not a stand alone. Read the early books for better understanding of what is happening. Without the understanding I was lost as to why Thor: The God of Thunder lost his worthiness. The ending is a cliffhanger.
The story is well told. The illustrations enhance the story. If you are into Thor you will enjoy it. It isn't my type of story so I'm not sure if I will finish the series or not.
