A sinister plot. A hidden city in the sky. A boy with an impossible choice.

Twelve year old Toby has little time for friends or football since his mum fell ill. All he wants is to stay at home and keep an eye on her.

But mysterious things are happening beyond his garden hedge. Who is the figure at the window behind the barbed wire fence? And why is there a strange woman in his attic with a broken broom and bothersome pet bat?

Toby becomes entangled in an adventure of flying dogs, sparking hiccups and dangerous escapes. An innocent young witch has been captured by a secretive organisation which will stop at nothing to find out how magic works. Toby must rescue her and and time is running out.
