This was a Disney-style audiobook based on the Marvel Movie of the same name. While I detest Disney's all-powerful mega-corporation status, and their lack of credit for the work people do on books like this, I do confess I'm a fan of the Marvel movies, and I was curious as to what they had done with this story which was aimed at younger children. In this case, the rewrite of the movie script was credited - to comic book author Jim McCann and the reading to narrator MacLeod Andrews who did a fine job.
It tells the story of Thor's battle against the Ragnarok beast, thinking he's won when he hasn't, of his return to Asgard to discover his mischievous stepbrother Loki has been impersonating Odin, and Odin's death, which permits the imprisoned sister Hela (whom Thor never knew he had) back into the world, and of her fight to take over Asgard and Thor's resistance to it - after he escapes confinement on a planet where the 'owner' captures tough visitors to make them fight one another for entertainment. It features the Hulk, and Valkyrie - an estimable addition to the Marvel pantheon of heroic women.
Apart from being tamed appropriately (and having some portions changed more than seemed necessary) it stuck to the story in the movie so it would make a decent read for young children who for whatever reason are not allowed to see the movie. So I commend this as a worthy listen.
