The Set-Up (Liars #3)

Jarli is competing in a robot battle when he is approached by sinister government agents. They want him to use his lie-detector app at a conference to prove the defence minister is telling the truth.
The minister may not be lying, but someone else is. When one of the delegates is attacked, Jarli becomes the prime suspect. He can't even use the Truth App to prove his innocence, because someone has hacked it.
Soon Jarli is on the run from the police, unable to trust anyone. Only one person could be behind this diabolical plan. Can Jarli stop Viper before it's too late?
The truth never stays buried for long...
