The Mind Hack - Peter Summersby

Reality is defined by what we, see, hear and feel. What would happen if you are unable to tell the difference between what is real and fake? When a computer AI starts testing a virtual holographic system on two unsuspecting men, they must race to find a way out of the computer that is hacking their minds and attacking New York. 

Tolbert, a simple room attendant is unexpectedly caught up in a holographic projection. He must decide what is real and what is not. The fate of the world hangs in the balance, as aliens and monsters ravage the centre of New York. An army of raptors led by trolls engage an alien menace. 
Striker, a computer gamer and hacktivist notices that a fellow gamer is being attacked in the game and seeks to find out what is going on. He must find and shut down the cause of it all before the world he knows is destroyed forever.
