This novel is set in future London, thousands of years from now. During this time there have been mutations in the humans, and a new race of Schrivens have appeared; they took over London for a long time, but now their time of reign is over and London is ruled by humans again. The Schrivens are thought have died out. Fever Crumb is a young woman working with the Order of Engineers, in fact she is the only woman working with them: this is because she was found by one of the engineers working there named Dr Crumb. Dr Crumb tells the story of how he found Fever to her because he doesn’t approve of lying.

‘Dr Crumb had been called out to dig on the Brick Marsh by an archaeologist named Chigley Unthank. […] There, among the bramble bushes, he had found a a baby in a basket, with an old blanket laid over and a label tied around her wrist upon which someone had written just four words:

HER NAME IS FEVER CRUMB’

But as the story goes on you find out more about Fever’s past and find that she isn’t just human, she is half Schriven, Granddaughter of the ruler of the Schrivens. Fever joins the Schriven and meets her mother who tells her of her past and how it is that she can remember things that haven’t happened in her life and how she knows the code to get into the vault that Godshawk himself made.

‘You were on the brink of death anyway, poor little thing. What had he to loose by putting the device in you head? He would have injected you at the same time with microscopic machines.’

Godshawk, Fever’s grandfather, had stored everything that happened in his life, into Fever’s brain.

I greatly enjoyed this book: I liked the way it gave you small pieces of information at a time, so you had to keep reading the book to find out the whole story and what was going to happen, This made it a real page-turner and it was worth the wait to find out what happens.

For these reasons I give this novel 8/10.
