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 activism 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 uncover if he tries? From the 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

    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.

    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!
