Girl gone viral

"For seventeen-year-old Opal Hopper code is magic. She can build entire worlds from scratch--shimmering lakes Mars craters any virtual experience her heart desires. But she can't code her dad back into her life. When he disappeared after her tenth birthday leaving only a cryptic note Opal tried desperately to find him. And when he never turned up she enrolled at a boarding school for technical prodigies and tried to forget. Until now. Because WAVE the world's biggest virtual reality platform has announced a contest where the winner gets to meet its billionaire founder. The same billionaire who worked closely with Opal's dad. The one she always believed might know where he went." --
