Pandemonium (Unabridged‪)‬

Kidnapped in broad daylight from a busy Edinburgh street, Hannah Wilson has no idea what her abductors want with her, as they chain her in the back of their van and speed out of the city. They tell her she's perfectly safe when she's terrified for her life. 

Transported to the far north of Scotland with dozens of others, all yanked from their lives across Britain, Hannah is taken to an isolated compound they call Pandemonium, which is an ultra-secure prison ruled by creatures that should exist only in nightmares - a place no one has survived for more than a few months. 

Hundreds of miles away from help, her family's lives at risk if she disobeys any order, Hannah knows the key to surviving her captivity is to bond with strangers and teach them all to refuse to be victims. But, she's running out of time to convince the other captives to take their fight to the black heart of the prison and its inhuman warden; Hannah is yet to discover she is not the only one about to start a war. 

In Pandemonium, all Hell is going to break out."
