To Catch a RAT: A psychological thriller (Darknet series Book 1)

She said she was being spied on. Now, she’s dead.
Emma's best friend Joss had a wild story to tell. She’d been hacked. She was being watched. She was in danger. No one believed her. Not even Emma. Now she’s dead.
The police write it off as accidental death, but Emma's not so sure. The more she learns, the deeper she’s drawn into a web of deceit and dark motives. Turns out Joss’s brother developed a revolutionary dark web application, one that people will kill to get their hands on. He's now in jail on a dodgy manslaughter charge.
And then there's Emma's boyfriend, who she discovers is lying about his identity. Now Emma’s the one in danger, and she's not sure who will believe her or who she can trust.
Joss’s murder was only the start.
