What a great thriller book. Definitely a page-turner! Had me hooked from the beginning . Would highly recommend you read it, definitely one of my favourite thrillers. As a huge thriller and suspense book lover, I had to read the book and it definitely did not disappoint.There was great characterisation, great suspense and a gripping story of technology and the horrifying way it can be misused. It was also set in the surprising town of Swindon, Wiltshire, Cornwall and finally Brittany where Silas, the police officer has to deal with the break up of his marriage, the disappearance of his son, slave trade in Swindon and the odd behavior of his ex-employee Kate. I would most definitely recommend this book to people who love a slow type burn in a book and dont mind the twist and turns. The book may get boring but as you keep reading it gets so much better and you just cant stop.
