Penguin presents the audiobook model of 9 Through the Nine Worlds by Rick Riordan, browse by Stephen Graybill, Devon Sorvari, Nick Chamian, Sile Bermingham, Paul Boehmer, Robertson Dean, Bahni Turpin, Will Damron and Larry Herron.

Travel the Nine Worlds together with your favourite people from the world of Magnus Run after in a brand-new group of adventures.

Discover out why Amir Fadlan hates clothing shopping in Midgard, observe how Mallory Willing discovers in icy Niflheim that insulting a dragon can be a good idea, and sign up for Alex Fierro as they play with flames (and a disco sword) in the house of the fire giants, Muspellheim.

But watch out for Thor, who’s jogging through all Nine Worlds thus he can log his million steps – and is raising a significant stink .
