The City was built on a sharp mountain that jutted improbably from the sea, and the sea kept trying to claim it back. That grey morning, once the tide had retreated, a whale was found on a rooftop.

When a mysterious boy washes in with the tide, the citizens believe he’s the Enemy – the god who drowned the world – come again to cause untold chaos.

Only Ellie, a fearless young inventor living in a workshop crammed with curiosities, believes he’s innocent.

But the Enemy can take possession of any human body and the ruthless Inquisition are determined to destroy it forever.

To save the boy, Ellie must prove who he really is – even if that means revealing her own dangerous secret . . .

I had heard a lot about this book before it was released, all of it good by the way, and having read the blurb which you can see above for yourself, I was completely sold. I had to buy it! Having finished it now, I can honestly say it is one of the best books I have read in a long time! The world that has been created and described in such fine detail is incredible and there is a beautiful map in the book so you can follow the characters around (I adore a good map in a book!). 

This is not a light-hearted, happy book; it is very much a darker story. Ellie, the main character, is wonderful; trying to save someone she doesn’t know and keep her friends safe but at the same time trying to hide her own dark and terrible secret. The Enemy is just that; utterly evil and without any sense of guilt about what they do to anybody else. This story twists and turns, taking you through the crumbling, damp streets of The City. You will be kept guessing right up until the end. As I said, this is quite a dark story and so will not be to everyone’s tastes; maybe some of the stronger readers in Year 5 and Year 6. If you do decide to give it a go; enjoy getting lost in The City (I know that I did!).
