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.” Then, 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.

Praise for Design Patterns in Ruby "Design Patterns in Ruby documents smart ways to resolve many problems that Ruby developers commonly encounter. Russ Olsen has done a great job of selecting classic patterns and augmenting these with newer patterns that have special relevance for Ruby. He clearly explains each idea, making a wealth of experience available to Ruby developers for their own daily work." —Steve Metsker, Managing Consultant with Dominion Digital, Inc. "This book provides a great demonstration of the key 'Gang of Four' design patterns without resorting to overly technical explanations. Written in a precise, yet almost informal style, this book covers enough ground that even those without prior exposure to design patterns will soon feel confident applying them using Ruby. Olsen has done a great job to make a book about a classically 'dry' subject into such an engaging and even occasionally humorous read." —Peter Cooper "This book renewed my interest in understanding patterns after a decade of good intentions. Russ picked the most useful patterns for Ruby and introduced them in a straightforward and logical manner, going beyond the GoF's patterns. This book has improved my use of Ruby, and encouraged me to blow off the dust covering the GoF book." —Mike Stok "Design Patterns in Ruby is a great way for programmers from statically typed objectoriented languages to learn how design patterns appear in a more dynamic, flexible language like Ruby." —Rob Sanheim, Ruby Ninja, Relevance Most design pattern books are based on C++ and Java. But Ruby is different—and the language's unique qualities make design patterns easier to implement and use. In this book, Russ Olsen demonstrates how to combine Ruby's power and elegance with patterns, and write more sophisticated, effective software with far fewer lines of code. After reviewing the history, concepts, and goals of design patterns, Olsen offers a quick tour of the Ruby language—enough to allow any experienced software developer to immediately utilize patterns with Ruby. The book especially calls attention to Ruby features that simplify the use of patterns, including dynamic typing, code closures, and "mixins" for easier code reuse. Fourteen of the classic "Gang of Four" patterns are considered from the Ruby point of view, explaining what problems each pattern solves, discussing whether traditional implementations make sense in the Ruby environment, and introducing Ruby-specific improvements. You'll discover opportunities to implement patterns in just one or two lines of code, instead of the endlessly repeated boilerplate that conventional languages often require. Design Patterns in Ruby also identifies innovative new patterns that have emerged from the Ruby community. These include ways to create custom objects with metaprogramming, as well as the ambitious Rails-based "Convention Over Configuration" pattern, designed to help integrate entire applications and frameworks. Engaging, practical, and accessible, Design Patterns in Ruby will help you build better software while making your Ruby programming experience more rewarding.

The Ministries of Secrets and Guilds, led by Ignatius Gall, are conspiring to put the Ministry of Trackers down for good—starting with Jack’s very existence as a Section 13.

Joined by their new friend Liu Fai, Jack and Gwen set out to stop Gall before he can uncover ancient Chinese artifacts, said to grant immortality. But a clockwork monster threatens them at every turn, and its ticking gears only serve as a reminder that Jack’s judgment day is fast approaching—and that he’s running out of time.
