Archie continues to develop both his locksmithing skills and his courage and we see the beginnings of a character with a destiny. I like Archie. His impulse to do good is borne from the loss of his foster brother in a tragic accident and he's taken on some guilt over this, which he longs to purge by standing up to be counted and to do the right thing. It's tremendously engaging and sympathetic. The overall arc of the story continues to be a mystery - what is Inez's mission exactly? What is Archie's role? Who wants to stop her and why? - but we can feel it being subtly hinted at as we read.
Of course: recommended. Right. I'm onto [[Archibald Lox and the Vote of Alignment by Darren Shan|book three]]. I'll be back with a review once I'm done!
If you enjoy stories of parallel worlds, you might also like [[The Nowhere Chronicles: The Double-Edged Sword by Sarah Silverwood]], which features knights with double-edged swords!
