Assured Destruction by Michael F. Stewart

You can learn a lot about someone looking through their hard drive... Sixteen-year-old Jan Rose knows that nothing is ever truly deleted. At least, not from the hard drives she scours to create the online identities she calls the Shadownet. Hobby? Art form? Sad, pathetic plea to garner friendship, even virtually? Sure, Jan is guilty on all counts. Maybe she’s even addicted to it. It’s an exploration. Everyone has something to hide. The Shadownet’s hard drives are Jan’s secrets. They're stolen from her family’s computer recycling business Assured Destruction. If the police found out, Jan’s family would lose its livelihood. When the real people behind Shadownet’s hard drives endure vicious cyber attacks, Jan realizes she is responsible. She doesn’t know who is targeting these people or why but as her life collapses Jan must use all her tech savvy to bring the perpetrators to justice before she becomes the next victim.
