I received this ARC copy from Netgalley in exchange for an honest review. So thank you netgalley and publishers.
This story is about an obsession and one man's attempt to unravel the mystery that destroyed his grandfather's life, set in a magical and intricately woven cityscape.
The synopsis is as follows :
In 1926, two brothers both loved Eleanor Raines, a promising young actress from the East End of London. But, along with Seth Lockwood, she disappeared, never to be seen again. Isaiah, Seth’s younger brother, refused to accept that she was just gone. 
It has been seventy years since and the brothers are long dead. But now their dark, twisted secret, threatens to tear the city apart. Seth made a bargain with Damiola, an illusionist, to make a life size version of his most famous trick, and hide away part of London to act as a prison out of sync with our time, where one year passes as one hundred. That illusion is Glass Town. And now its walls are failing. 
Reminiscent of Clive Barker’s Weaveworld and Neil Gaiman’s American Gods, Savile brings out the magic in the everyday. Glass Town is full of gritty urban landscapes, realistic characters, conflict, secrets, betrayals, magic, and mystery.
This was an interesting book, I had mixed feelings, I enjoyed it but I felt it was just a bit too slow for me at first.. 4 stars.
