Circle of Legends - Asgard

Asgard is the second instalment of Aiden Weir's Circle of Legends series.

In Peru, Ariel and Stephen encounter a mysterious old man and are immediately suspicious. Not only does he speak fluent Atlantian, but he also claims to have something vitally important to show them in the ruins of Machu Picchu.

In Asia, Langton is hot on the trail of an assassin who has stolen the final component of David's Athena Project, a rare red crystal.

In Santorini, Marina is unexpectedly relieved of command of the Oceanus and sent on a secret assignment by Alex.

Could all this have something to do with the strange readings emanating from the Arctic Circle?
