Echoes | Tisdall, Laura

'There is truth to be shared. Let us begin...' Volatile mathematical genius Mallory Park is living two lives. In one, she is balancing senior year with looking after her little brother and troubled ex-Marine father; in the other, she spends her nights glued to her laptop, breaking into some of the world's most secure systems as the hacker Echo Six. As part of a corruption-exposing cyber network called the Forum, Mallory is far more at ease among the codes and hidden identities of her online world than she has ever been in the real one, but when other hackers start to go missing, she finds herself caught up in a web of secrets that could have repercussions far beyond both. When anyone can be a name on a screen, how do you know who to trust? (UK First Edition)
