Product description

It’s a normal Friday evening for Elliot – until the police knock on the door and tell him that his mum’s in serious trouble! A security video shows her breaking into a giant pharmaceutical company on behalf of the environmental action group ANTIDOTE. Elliot can hardly believe it. His mum’s a secretary – not a spy! But how on earth can he prove it? And what sinister secrets will he reveal if he tries? From the multi-award-winning Malorie Blackman, this tense, topical techno-thriller will leave you with your heart in your mouth.

“Malorie Blackman has successfully rebooted the ripping yarn.” The Times

“A gripping techno-thriller.” Independent on Sunday

    Thrilling, I loved reading it. An absolute cliff hanger.

    I couldnt guess who the traitor of antidote was at all. Elliot is always complaining about his mom’s boring job but then he finds she is a spy.

    this book is a new book in my class book corner. My friend is reading it at the moment. I was about to read it though. It sounds really good.

    I love this book because it always keeps you guessing and you can never expect what is comign next. The tension and excitement always builds up and you can’t wait until you read the next page! I adored the ending! Perfect for people who love a good shock!
