There’s a fine line between innocence and guilt. An even finer line between justice and revenge.

Shy and sensible Laura prefers the company of her books to the real world – let alone that cesspit online. But when her best friend Emily becomes the victim of horrific cyberbullying, she makes it her all-engulfing mission to track down the worst culprits using her finely-tuned data skills.

Petite corporate financier Suki is about to outshine the stupid boys at her firm: she’s leading the acquisition of Edinburgh’s most exciting start-up. If only she could get its brilliant, but distracted, co-founder Laura to engage.

Event planner Claire is left to salvage the start-up’s annual conference after her colleague Emily fails to return to work. She’s determined to get a promotion out of it, but her boss isn’t playing ball.

But with emotions running high, will the punishments fit the crimes?
