The Oversight: A mystery of witch-hunters, magicians and mirror-walkers - Couverture souple

Exciting, exhilarating, scary and moving in equal measure, The Oversight is a teeming world of dark deeds and dark magics, brilliantly realised. This feels like the start of something amazing (M. R. Carey, author of THE GIRL WITH ALL THE GIFTS)

A highly entertaining fantasy that promises a trilogy worth sinking your teeth into (SciFiNow)

Fletcher's Victorian London is juicily vivid, and laced with macabre Dickensian wit. There's a real sense of grim danger, both natural and unnatural, hungrily awaiting the slightest mis-step (Frances Hardinge, Costa Book of the Year winner)

Told in a kind of compelling and hypnotic poesie that I just lapped up . . . I'll certainly be reading the next one (Cory Doctorow BoingBoing.net)

A richly atmospheric and intensely readable slice of Victoriana, with a splendidly eerie sense of the way the unearthly lies cheek-by-jowl with the mundane (Adam Roberts)

The Oversight is - and let's be clear here - something very special . . . It's oh so moreish a morsel. I'd read a prequel this evening, a sequel as soon as. (Niall Alexander Tor.com)

A remarkable combination of British folklore, brisk pacing and wide-ranging imagination (Kirkus Reviews)

Richly atmospheric (the evil lurks in the background of every paragraph), the book should be a big hit with supernatural-fantasy readers ... the second book can't come soon enough (Booklist (starred review))

Utterly enthralling: Charles Dickens meets Susanna Clarke (Lou Morgan)
