This is a truly amazing book.
I have read many of the Chris Ryan books in the past aimed at the adult readers and this is the first time I have ventured into the 'teenage fiction' Chris Ryan books.
The plot is amazing and follows a 13 year old child from Macclesfield through his fight for survival on the flooded streets of London as a ship crashes into the Thames flood barrier in bad weather causing Greater London to be completely flooded with amazing descriptions, making it possible to imagine exactly what the devestation is like.
The realism is beyond belief and at times I could almost feel water around my feet it is that real! The story is not just about his fight for survival, but the effects Global warming has on the Earth. It made me rather worried about the future situation we may face if we continue to act as we do with our climate as the events in this book may be more common in the future.
Overall, the book is highly realistic, has one of the best storylines I have ever read and is highly realistic.
If you liked the 'Alpha Force' series by Chris Ryan, 'CHERUB' series by Robert Muchamore or 'Alex Rider' series by Anthony Horowitz you would love this book.
I would strongly recommend it.
