Penguin presents the audiobook edition of 9 From the Nine Worlds by Rick Riordan, read by Stephen Graybill, Devon Sorvari, Nick Chamian, Sile Bermingham, Paul Boehmer, Robertson Dean, Bahni Turpin, Will Damron and Larry Herron. Travel the Nine Worlds with your favourite characters from the world of Magnus Chase in a brand-new series of adventures. Find out why Amir Fadlan hates clothes shopping in Midgard, see how Mallory Keen learns in icy Niflheim that insulting a dragon can be a good idea, and join Alex Fierro as they play with fire (and a disco sword) in the home of the fire giants, Muspellheim. 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 . . .
