Hacker by Malorie Blackman

I loved every moment of reading Hacker. Vicky's father gets blamed; a million pounds has been put into his account. Vicky and her annoying brother Gib investigate by logging onto the Live account of the bank where her dad works and checking each and every one of where the staff was on the system. Lucky for Vicky, she is a computing genius, but it will test her hacking skills to the limit. She could end up in as much trouble as her dad...or worse.
I admit, I did copy that off the blurb but at least you can see it here.
This is a great book to read on a duvet day, plus its also the winner of the Young Telegraph/Gimme 5 award.
Hope you take my advice and pick this book as your Sunday read.☺️
