The Hammer of Thor continues thr story of Magnus Chase et al., following on from the Sword of Summer. Though I did enjoy this one - it's fun and light and Magnus makes excellent narrator - I feel like it's not quite as good as the first book. Somehow, the plot is less engaging and I was not as drawn into it as I was with the Sword of Summer. 
 I liked our new character - Alex Fierro - but I don't really feel that we got to know her and I still feel more attachment to other, more minor characters. I feel that it would have been better to either have Alex in there from the beginning or not include her at all and give some more screen-time to one of the more minor characters from the first book (T.J.! T.J.!). 
 Ah well, I suppose I'll have a chance to become besotted with Alex in the last book (Hammer of Nails?) and I am rooting for her and Magnus to JUST KISS ALREADY, though not as strongly as I perhaps should be. 
 All in all, though, it was good fun. Maybe I'm just getting too old for this running about lark.
