Eoin Colfer always writes a good tale and in this one you have an orphan, Victorian London, magic, and an assassination, good stuff for kids who crave fantasy and adventure.

Intriguing and well-paced. A well-developed start to the WARP series world and characters. Riley is an engaging main character and the reader finds themselves eager to follow his journey.

Another gem from Eoin Colfer! Fantastic storylines seem completely plausible and his characters come off the page fully realized right from the beginning.
I'm excited to recommend this book for my students when they come asking for suggestions of what to read next. I immediately went out and got the next books in the series and loved them, too!

Excellent start to the new series with both modern and historical storylines and some very strong and relatable characters. Colfer's great sense of humour shines through, and readers will love the fast-paced narrative.

I wanted to like this book.  After reading and loving Artemis Fowl, I wanted to like this new series just as much. But perhaps I'm too old, perhaps fantasy for younger readers isn't my thing anymore? Whatever the reason I just didn't get on with this book. Through no fault of it's own, I'm sure.
