"I really enjoyed this book and I would recommend it to any Minecraft and computer geeks of any age." "A great story for today's child of 9+." Amazon.co.uk reviewers March 2014. A book for children aged 9-13. The Cracker Hacker, Jack MacLuckie, loves Minecraft and spy missions but faces sister trouble. A coding genius and budding games developer Jack is a modern day kind of superhero (but without that silly pants over the trousers thing). As his sister Bella falls prey to a nasty cyberbully, Jack is faced with a dilemma: Should he use his hacking talents to bail her out, or sort it out in real life? As he tries to solve the problem Jack soon discovers that he is not the only one in the family keeping secrets. Why is Mum suddenly so addicted to her Grumpy Pigeons game on her mobile phone? Why is Dad always disappearing? And why does Jack owe his life to Bella? Jack soon learns that online profiles and real life dramas can make one tricky mix. Will he ever pick his way out of the mess? Jack likes: Minecraft, coding, his sister Bella, Aikido, visiting Bletchley Park, reading his great grandad's war diaries, unicorns and biscuits. Dislikes: Oliver (the noob), homework, sun cream, dog poo and tinned sardines. Ambition in life: To be the next Notch. "Some of the bullies at school call me a hacker as an insult. I know they're really jealous. I'm just a valiant seeker of information, saving people from danger and harm. Someone who needs a little trumpet fanfare to make an entrance. A kind of modern day superhero, but without the cape. And not wearing pants on top of my trousers. Definitely not the pants thing." Recommended for age 9+.
