ACID, which stands for Agency for Crime Investigation and Defence, is a sinister police force that runs the UK, now renamed the IRB. Their reign is brutal, and they watch everyone and everything. The building of this terrifying world is impressive - set one hundred years in the future in a Big Brother style society. The mystery of Jenna’s past runs throughout the novel and I was always eager to learn more. I really liked the newspaper reports inserted into the book, which give insight into what’s happening away from Jenna. From the beginning, the book hits you with extreme danger, a touch of romance, and exhilarating plot twists that build to a spectacular finish.
