Girl gone viral
(Book)

"For seventeen-year-old Opal Hopper, code is magic. She builds entire worlds from scratch: Mars craters, shimmering lakes, 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, Opal 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. The one who maybe even murdered him. What begins as a small data hack to win the contest spirals out of control when Opal goes viral, digging her deeper into a hole of lies, hacks, and manipulation. How far will Opal go for the answers--or is it the attention--she's wanted for years?" --from front jacket flap.
