Magnus Chase 9 from the new worlds. Rick Riordan. 2018.

Travel the nine worlds in a brand-new set of adventures.

Find out why Amir Fadlan hates clothes shopping in Midgard, see how Mallory Keen leans in icy Nifheim that insulting a dragon can be a good idea, and join seven other favourite characters from the world of Magnus Chase.

But watch out for Thor, who is jogging through all Nine Worlds so he can log his million steps - and is raising quite a stink.
