Publisher's Summary

Jack and Gwen are back in this dynamic follow-up to The Lost Property Office.

It's been a year since Jack Buckles discovered the Keep beneath Baker Street, an underground tower no Section Thirteen was ever supposed to see; a year since his dad fell into a coma. Nothing has been the same since. Jack's tracker abilities are on the fritz, Gwen's not speaking to him, and, what's worse, there's a pounding voice in his head calling for "the flame".

Jack and Gwen are framed for the theft of a historic crown jewel - the Black Prince's Ruby, one of three cursed rubies said to bring knowledge, loyalty, and the command of nations to whomever wields them all. Now they must retrieve the other jewels before the true thief does or risk unleashing a reign of terror unlike anything history's ever seen.

Fun adventure with a deeper twist

Jack and Gwen are back with a new cast, in a story that reaches beyond London. We go deeper into the Ministries of Secrets and Dragons, and we chase a thief through an epic Thieves Guild, all the way to Moscow.

Jack develops a new, extremely cool skill, but he also deals with a type of addiction (via an artifact) and must come to grips with a tragic family issue (unsaid to avoid spoilers). All in all, this is a dynamic, action-packed story that gives the hero a deeper emotional struggle to contend with.

In the spirit of reconciliation, Audible Australia acknowledges the Traditional Custodians of country throughout Australia and their connections to land, sea and community. We pay our respect to their elders past and present and extend that respect to all Aboriginal and Torres Strait Islander peoples today.
