Jonah Wish is in an elite team of teenage thieves lead by master criminal Nathaniel Coldhardt. Coldhardt plans every mission with absolute precision. So when Jonah and the rest of the team break into a highly secure compound to steal a precious sword, they can't quite beleive it when they discover that someone has beaten them to it. Is Coldhardt losing his touch?

But there's worse to come. A member of the team is kidnapped - from their secret base, no less. Who has taken her and why? And is her abduction linked to the missing sword? There have been rumours in the underworld about a shadowy organisation called the Sixth Sun, who have shown interest in the sword, and now it's time for Jonah to do what he's best at: put the pieces together and decode the mystery. Literally.

In a mission which takes him from Guatemala to the jungles of Mexico, Jonah must rely on his unusual talent for codebreaking to try and decipher the connection before it's too late.
